Sequelae or resulting conditions
3. Where a person—
(a) is or was in employed earner's employment and a disease is or was prescribed under the Act and these regulations in relation to him in such employment; and
(b) is suffering from a condition which, in his case, has resulted from that disease;
the provisions of Chapter V of Part II of the Act and of these regulations shall apply to him as if he were suffering from that disease, whether or not the condition from which he is suffering is itself a prescribed disease.

Presumption that a disease is due to the nature of employment
4. (1) Where a person has developed a disease which is prescribed in relation to him in Part I of Schedule 1 hereto, other than the disease numbered A10, B5, D1, D2, D4 and D5 in that Schedule, that disease shall, unless the contrary is proved, be presumed to be due to the nature of his employed earner's employment if that employment was in any occupation set against that disease in the second column of the said Part and he was so employed on, or at any time within one month immediately preceding, the date on which, under the subsequent provisions of these regulations, he is treated as having developed the disease.
(2) Where a person in relation to whom tuberculosis is prescribed in paragraph B5 of Part I of Schedule 1 hereto develops that disease, the disease shall, unless the contrary is proved, be presumed to be due to the nature of his employed earner's employment if the date on which, under the subsequent provisions of these regulations, he is treated as having developed the disease is not less than 6 weeks after the date on which he was first employed in any occupation set against the disease in the second column of the said Part and not more than 2 years after the date on which he was last so employed in employed earner's employment.

PART III DATE OF ONSET AND RECRUDESCENCE

Development of disease
5. If on a claim for benefit under Chapter V of Part II of the Act in respect of a prescribed disease a person is found to be or to have been suffering from the disease, or to have died as the result thereof, the disease shall, for the purposes of such claim, be treated as having developed on a date (hereafter in these regulations referred to as “the date of onset”) determined in accordance with the provisions of the next 2 following regulations.

Date of onset
6. (1) For the purposes of the first claim in respect of a prescribed disease suffered by a person, the date of onset shall be determined in accordance with the following provisions of this regulation, and, save as provided in regulation 7, that date shall be treated as the date of onset for the purposes of any subsequent claim in respect of the same disease suffered by the same person, so however that—
(a) subject to the provisions of section 117(4), as modified by paragraph 1 of Schedule 3 to the Adjudication Regulations, any date of onset determined for the purposes of that claim shall not preclude fresh consideration of the question whether the same person is suffering from the same disease on any subsequent claim for or award of benefit; and
(b) if, on the consideration of a claim, no award of benefit is made, any date of onset determined for the purposes of that claim shall be disregarded for the purposes of any subsequent claim.
(2) Where the claim for the purposes of which the date of onset is to be determined is—
(a) a claim for sickness benefit made by virtue of section 50A of the Act by a person to whom regulation 8(1) applies (except in respect of pneumoconiosis, byssinosis, diffuse mesothelioma, occupational deafness, occupational asthma, lung cancer or bilateral diffuse pleural thickening) the date of onset shall be the first day on which the claimant was incapable of work as the result of the disease on or after 5th July 1948;
Section 50A was inserted by the Social Security and Housing Benefits Act 1982 (c.24), section 39(4) .
(b) a claim for disablement benefit (except in respect of occupational deafness), the date of onset shall be the day on which the claimant first suffered from the relevant loss of faculty on or after 5th July 1948; and the date of onset so determined shall be the date of onset for the purposes of a claim for sickness benefit made by virtue of section 50A of the Act in respect of pneumoconiosis, byssinosis, diffuse mesothelioma, occupational asthma, lung cancer or bilateral diffuse pleural thickening;
(c) a claim for disablement benefit in respect of occupational deafness, the date of onset shall be the day on which the claimant first suffered from the relevant loss of faculty on or after 3rd February 1975; or, if later—
(i) 3rd September 1979 in the case of a claim made before that date which results in the payment of benefit commencing on that date, and
(ii) in any other case, the date on which such claim is made as results in the payment of benefit; or
(d) a claim for death benefit, the date of onset shall be the date of death.

Recrudescence
7. (1) If a person after having been awarded benefit in respect of a prescribed disease other than pneumoconiosis, byssinosis, diffuse mesothelioma, occupational deafness, occupational asthma, lung cancer or bilateral diffuse pleural thickening suffers from another attack of the same disease, or dies as a result thereof, then—
(a) if the further attack commences or the death occurs during a period taken into account by an assessment of disablement relating to such a previous award (which period is in this regulation referred to as a “relevant period”) the disease shall be treated as a recrudescence of the attack to which the relevant period relates, unless it is otherwise determined in the manner referred to in the following sub-paragraph;
(b) if the further attack commences or the death occurs otherwise than during a relevant period, or if it is determined in the manner provided in Part IX of the Adjudication Regulations that the disease was in fact contracted afresh, it shall be treated as having been so contracted.
(2) For the purposes of paragraph (1), a further attack of a prescribed disease shall be deemed to have commenced on the date on which the person concerned was first incapable of work or first suffered from the relevant loss of faculty, whichever is earlier, as a result of that further attack.
(3) Where, under the foregoing provisions of this regulation, a disease is treated as having been contracted afresh, the date of onset of the disease in relation to the fresh contraction shall be the date on which the person concerned was first incapable of work or first suffered from the relevant loss of faculty, whichever is earlier, as a result of the further attack, or in the event of his death, the date of death.
(4) Where, under the provisions aforesaid, a disease is treated as a recrudescence, any assessment of disablement in respect of the recrudescence during a period taken into account by a previous assessment of disablement shall be by way of review of the assessment relating to the relevant period, and the review shall be subject to the provisions of regulation 49 of the Adjudication Regulations.
(5) This regulation shall not apply in relation to a claim for sickness benefit made by virtue of section 50A of the Act except where such a claim is made by a person to whom regulation 8(1) applies.

Workmen's compensation cases
8. (1) If under the foregoing provisions of this Part of these regulations a date of onset has to be determined for the purposes of a claim for benefit in respect of a prescribed disease, other than pneumoconiosis or byssinosis, suffered by a person to whom compensation under the Workmen's Compensation Acts has been awarded or paid in respect of the same disease and, at the date of such claim for benefit, or, if it is a claim for death benefit, at the date of death—
(a) that person was in receipt of weekly payments in respect of such compensation; or
(b) any liability or alleged liability for such compensation had been redeemed by the payment of a lump sum, or had been the subject of a composition agreement under the provisions of the said Acts;
the disease in respect of which the claim is made shall be treated for the purposes of these regulations as a recrudescence of the disease in respect of which such compensation was awarded or paid and not as having developed on or after 5th July 1948 unless it is determined in the manner provided in Part IX of the Adjudication Regulations that the disease was in fact contracted afresh.
(2) If it is determined as provided in the foregoing paragraph that the disease was contracted afresh, or if compensation is not being or has not been paid as provided in sub-paragraph (a) or (b) thereof, the date of onset shall be determined in accordance with regulations 5 to 7 as if no compensation under the Workmen's Compensation Acts had been paid in respect of that disease.
(3) If the date of onset has to be determined as aforesaid in respect of pneumoconiosis or byssinosis suffered by a person to whom compensation has been awarded or paid in respect of the same disease or in respect of whose death compensation has been awarded or paid under the provisions of any scheme made under the provisions of the Workmen's Compensation Acts relating to compensation for silicosis, asbestosis, pneumoconiosis or byssinosis, the disease in respect of which the claim is made shall (subject to the provisions of regulation 9(2)(b)) be treated for the purposes of these regulations as not having developed on or after 5th July 1948.
(4) If, after the date of a claim for benefit in respect of a prescribed disease, the claimant receives a weekly payment of compensation in respect of that disease under the Workmen's Compensation Acts which he was not receiving at the date of such claim, or if the amount of any such weekly payment which he was receiving at that date is increased, then any decision on any question arising in connection with that claim, if given before the date of, or in ignorance of the fact of, the receipt of such weekly payment or increased weekly payment, may be reviewed as if it had been given in ignorance of a material fact, and on such review the question may be decided as if the claimant had been in receipt of such weekly payment or increased weekly payment at the date of the claim, and the foregoing provisions of this regulation shall apply accordingly.
(5) For the purposes of this regulation, a person shall be deemed to be, or to have been, in receipt of a weekly payment of compensation if—
(a) he is or was in fact receiving such payment; or
(b) he is or was entitled thereto under an award or agreement made under the Workmen's Compensation Acts.
(6) This regulation shall apply to compensation under any contracting out scheme duly certified under the Workmen's Compensation Acts as it applies to compensation under those Acts.

Re-employment of pneumoconiotics and special provisions for benefit (workmen's compensation cases)
9. (1) Where a person—
(a) has been certified by a medical board under the provisions of any scheme made under the provisions of the Workmen's Compensation Acts to be suffering from silicosis or pneumoconiosis not accompanied in either case by tuberculosis and has been awarded or paid compensation under the provisions of any such scheme, and by reason of such certification has been suspended from employment in any industry or process or in any particular operation or work in any industry, and
(b) wishes to start work in employed earner's employment in any occupation involving work underground in any coal mine, or the working or handling above ground at any coal mine of any minerals extracted therefrom, or any operation incidental thereto, being an occupation in which he is allowed by certificate of the medical board under the provisions of the scheme to engage,
he shall, before starting any such work, submit himself under arrangements made or approved by the Secretary of State for medical examination by a special medical board.
(2) Where a person submits himself for medical examination in accordance with the provisions of the foregoing paragraph, the provisions of the Act and the regulations made thereunder shall apply to him subject to the following modifications:—
(a) The special medical board shall determine at what degree the extent of disablement resulting from pneumoconiosis at the time of their examination would be assessed in his case, if that question had been referred to them for determination by an adjudication officer on consideration of a claim for disablement benefit, and the provisions of the Act and of the Adjudication Regulations which relate to the determination of disablement questions (other than the provisions relating to the review of assessments on the ground of unforeseen aggravation) shall apply as if the decision of the special medical board were a final assessment of the extent of disablement.
(b) Where the extent of disablement has been determined in his case in accordance with the provisions of the foregoing sub-paragraph by a special medical board or a medical appeal tribunal, and he starts any such work as is mentioned in the foregoing paragraph, the provisions of regulation 38(a) (periodical examinations) shall apply to him as if he were making a claim for benefit in respect of pneumoconiosis, and the provisions of regulation 8(3) (pneumoconiosis shall in certain cases be treated as not having developed on or after 5th July 1948) shall cease to apply to him as from the date of starting such work.
(c) If, after having started work as aforesaid, he makes a claim at any time for disablement benefit in respect of pneumoconiosis, the extent of disablement in his case shall be assessed as if, to the extent certified in the decision of the special medical board or medical appeal tribunal given under sub-paragraph (a) of this paragraph, his disabilities resulting from pneumoconiosis were contracted before the date of onset and were not incurred as the result of the relevant loss of faculty.
(d) A person to whom a disablement pension is payable in respect of an assessment made in accordance with the provisions of the last foregoing sub-paragraph and who requires constant attendance shall, if the sum of that assessment and the assessment made in his case in accordance with the provisions of sub-paragraph (a) of this paragraph is not less than 100 per cent, have the like right to payments in respect of the need of such constant attendance as if the disablement pension were payable in respect of an assessment of 100 per cent.
(3) Where a person to whom sub-paragraph (a) of paragraph (1) applies has started any such work as is mentioned in sub-paragraph (b) thereof without having submitted himself for medical examination in accordance with the provisions of that paragraph, he may nevertheless, at any time whilst he is engaged in any such work, so submit himself for medical examination, and the provisions of the foregoing paragraph shall, if he continues thereafter to be engaged in any such work, apply to him as if he had started that work immediately after the medical examination.
(4) The Secretary of State, in making or approving any such arrangements for medical examination of any person as are mentioned in paragraph (1) shall, as far as possible, co-ordinate those arrangements with any arrangements for medical examination of that person made or approved under Part V of these regulations or under the Workmen's Compensation Acts.

PART IV APPLICATION OF CHAPTERS IV AND VI OF PART II OF THE ACT AND OF REGULATIONS MADE THEREUNDER

Definition of “relevant disease”
10. In this Part of these regulations, unless the context otherwise requires, the expression “relevant disease” means, in relation to any claim for benefit in respect of a prescribed disease, the prescribed disease in respect of which benefit is claimed, but does not include any previous or subsequent attack of that disease, suffered by the same person, which, under the provisions of Part III of these regulations, is or has been treated—
(a) as having developed on a date other than the date which, under the said provisions, is treated as the date of onset for the purposes of the claim under consideration;
(b) as a recrudescence of a disease for which compensation has been paid or awarded under the Workmen's Compensation Acts.

Application of Chapters IV and VI of Part II of the Act
11. The provisions of Chapters IV and VI of Part II of the Act which relate to industrial injuries benefit and sickness benefit made by virtue of section 50A of the Act shall, in relation to prescribed diseases, be subject to the following provisions of this Part of these regulations, and, subject as aforesaid, to the additions and modifications set out in Schedule 2 hereto.

Application of Claims and Payments Regulations and Benefit Regulations
12. (1) Save in so far as they are expressly varied or excluded by, or are inconsistent with, the provisions of this Part of these regulations or of regulation 25 or 36, the Claims and Payments Regulations and the Benefit Regulations shall apply in relation to prescribed diseases as they apply in relation to accidents.
(2) Save as provided in this Part of these regulations or where the context otherwise requires, references in the aforesaid regulations to accidents shall be construed as references to prescribed diseases, references to the relevant accident shall be construed as references to the relevant disease, references to the date of the relevant accident shall be construed as references to the date of onset of the relevant disease, and in regulation 17 of the Benefit Regulations (increase of disablement pension in cases of special hardship), the reference to the effects of the relevant injury shall be construed as a reference to the effects of the relevant disease.

Benefit not payable in cases covered by the Industrial Injuries and Diseases (Old Cases) Act 1975
13. Benefit shall not be payable by virtue of the provisions of these regulations in respect of the incapacity, disablement or death of any person as a result of any disease, if an award of benefit under the provisions of any Scheme made under the Industrial Injuries and Diseases (Old Cases) Act 1975 (not being an award which is subsequently reversed on review) has at any time been made in respect of any attack of the disease suffered by him, or in respect of his death.

Diseases contracted outside Great Britain
14. For section 50(5) (accidents happening outside Great Britain) there shall be substituted the provision that, subject to the provisions of sections 129, 131 and 132, for the purpose of determining whether a prescribed disease is, or, under the provisions of Part II of these regulations is to be presumed to be, due to the nature of the person's employed earner's employment, that person shall be regarded as not being or as not having been in employed earner's employment during any period for which he is or was outside Great Britain, and accordingly benefit shall not be payable in respect of a prescribed disease which is due to the nature of employment in an occupation in which the person has only been engaged outside Great Britain.

Assessment of extent of disablement
15. For the purposes of paragraph 1(b) of Schedule 8 (disabilities to be taken into account in assessing the extent of the claimant's disablement) and of regulation 11 of the Benefit Regulations (which further defines the principles of assessment of disablement), an injury or disease other than the relevant disease shall be treated as having been received or contracted before the relevant disease if it was received or contracted on or before the date of onset, and as having been received or contracted after the relevant disease if it was received or contracted after that date.

Death benefit for woman having care of deceased's children
16. (1) Section 73 (the entitlement to death benefit of a woman having the care of a child or children in respect of whom the deceased was entitled to child benefit) shall have effect as if for references to the date of the relevant accident there were substituted references to the relevant date.
(2) For the purposes of the last foregoing paragraph, the relevant date means the date of onset of the relevant disease, or the first day of the period of 26 weeks ending with the date of death, whichever is the later.

Special provisions as to determination of regular occupation in relation to persons claiming an increase of benefit for special hardship
17. Where a person who is or has been awarded disablement benefit in respect of a prescribed disease establishes that he has abandoned any occupation as a result of the relevant disease at any time after having been employed in employed earner's employment in any occupation prescribed for that disease but before the first day for which he is or has been awarded disablement benefit in respect of that disease, then for the purpose of determining his right to, or the rate of, an increase of that benefit under section 60 (increase of disablement benefit for special hardship), any occupation he has so abandoned may be treated as his regular occupation for the purposes of section 60.

Exception from requirements as to notice
18. Regulation 24 of the Claims and Payments Regulations (giving of notice of accidents in respect of which benefit may be payable) shall not apply in relation to prescribed diseases.

Provisions as to medical examination
19. Those provisions of section 89(1) and (2) which relate to the obligation of claimants to submit themselves to medical examination for the purpose of determining the effect of the relevant accident shall apply also to medical examinations for the purpose of determining whether a claimant or beneficiary is suffering or has suffered from a prescribed disease, and regulation 26 of the Claims and Payments Regulations shall be construed accordingly.

PART V SPECIAL PROVISIONS AS TO PNEUMOCONIOSIS, BYSSINOSIS, OCCUPATIONAL DEAFNESS AND CERTAIN OTHER DISEASES

SECTION A BENEFIT

Special conditions for disablement benefit for pneumoconiosis, byssinosis and diffuse mesothelioma
20. (1) No disablement gratuity shall be payable in respect of pneumoconiosis, byssinosis or diffuse mesothelioma, but if in any case the extent of disablement is such that, when assessed in accordance with section 57 (disablement benefit), it amounts to less than 20 per cent, the beneficiary shall, subject to the proviso to section 57(6) , be entitled to a disablement pension for the period taken into account by the assessment, payable, if such assessment does not exceed 10 per cent, at the weekly rate specified in Schedule 4 to the Benefit Regulations (rate of disablement pension payable in lieu of disablement gratuity) for a degree of disablement of less than 11 per cent but not less than 6 per cent, and in any other case at the weekly rate so specified for a degree of disablement of less than 20 per cent but not less than 16 per cent.
(2) Section 78(4)(b), in so far as it provides that disablement benefit shall not be payable in respect of byssinosis unless the claimant is found to be suffering from loss of faculty which is likely to be permanent, shall not apply.
(3) Notwithstanding paragraph 4(a) of Schedule 8 (period to be taken into account by an assessment of the extent of the claimant's disablement), the period to be taken into account by an assessment of the extent of the claimant's disablement in respect of byssinosis, if not limited by reference to the claimant's life, shall not be less than one year.

Pneumoconiosis—effects of tuberculosis
21. Where any person is found to be suffering from pneumoconiosis accompanied by tuberculosis, the effects of the tuberculosis shall be treated for the purposes of Chapter V of Part II of the Act and of these regulations as if they were effects of the pneumoconiosis.

Pneumoconiosis—effects of emphysema and chronic bronchitis
22. (1) Where any person is disabled by pneumoconiosis or pneumoconiosis accompanied by tuberculosis to an extent which would, if his physical condition were otherwise normal, be assessed at not less than 50 per cent, the effects of any emphysema and of any chronic bronchitis from which that person is found to be suffering shall be treated for the purposes of Chapter V of Part II of the Act and of these regulations as if they were effects of the pneumoconiosis.
(2) Where, on a claim for death benefit, the question arises whether the extent of a person's disablement resulting from pneumoconiosis or from pneumoconiosis accompanied by tuberculosis would, if his physical condition were otherwise normal, have been assessed at not less than 50 per cent—
(a) if there has been no assessment of disablement resulting from pneumoconiosis or from pneumoconiosis accompanied by tuberculosis made during the person's life, or if there is no such assessment current at the time of death, that question shall be determined by a medical board and the provisions of the Act shall apply as if such question were a disablement question;
(b) if there is an assessment of disablement resulting from pneumoconiosis or from pneumoconiosis accompanied by tuberculosis current at the time of the person's death, that question shall be treated as having been determined by the decision of the medical board or medical appeal tribunal, as the case may be, which made such assessment.

Increase of benefit for special hardship—special provision for penumoconiosis cases
23. Where a beneficiary in receipt of a disablement pension in respect of pneumoconiosis receives advice from a special medical board that in consequence of the disease he should not follow his regular occupation unless he complies with certain special restrictions as to the place, duration or circumstances of his work, or otherwise, then for the purpose of determining whether he fulfils the conditions laid down in section 60(1) (increase of disablement pension for special hardship) and for that purpose only—
(a) the beneficiary shall be deemed, unless the contrary is proved by evidence other than the aforesaid advice—
(i) to be incapable of following his regular occupation and likely to remain permanently so incapable, and
(ii) to be incapable of following employment of an equivalent standard which is suitable in his case;
(b) where the beneficiary has ceased to follow any occupation to which the aforesaid special restrictions were applicable, the fact that he had followed such an occupation in the period between the date of onset of the disease and the date of the current assessment of his disablement, or for a reasonable period of trial thereafter, shall be disregarded.

Special requirement for pneumoconiosis claimants in unscheduled occupation cases
24. (1) Part IX of the Adjudication Regulations shall apply to any claim for disablement benefit in respect of pneumoconiosis by a person in relation to whom the disease is prescribed by virtue of regulation 2(b)(ii) subject to the modification that if the claimant fails to show to the satisfaction of the adjudication officer that there is reasonable cause for suspecting that the claimant is suffering or has suffered from the disease the adjudication officer shall on that ground, and without referring the diagnosis question as provided in regulation 43(2) of the Adjudication Regulations, determine that an award cannot be made.
(2) The provisions of the last foregoing paragraph shall apply to a social security appeal tribunal and a Commissioner as they apply to the adjudication officer.

Time for claiming benefit in respect of occupational deafness
25. (1) Regulation 14 of the Claims and Payments Regulations (time for claiming benefit) shall not apply in relation to occupational deafness except in relation to a claim for sickness benefit payable by virtue of section 50A.
(2) Subject to regulation 27(1)(c), disablement benefit, or sickness benefit payable by virtue of section 50A of the Act, shall not be paid in pursuance of a claim in respect of occupational deafness which is made later than 5 years after the latest date, before the date of the claim, on which the claimant worked in an occupation prescribed in relation to occupational deafness unless—
(a) the claimant has been employed in one or more of the occupations so prescribed for a period or periods amounting in aggregate to not less than 10 years, and
(b) that period or the last of those periods ended on or after 8th October 1977, and
(c) the claim is made within the period of one year beginning on 3rd October 1983, and
(d) either—
(i) the claimant, not being a person to whom regulation 27(1)(c) applies, has not within the period of 3 years before the claim was made previously made a claim which was disallowed because he was not suffering from occupational deafness, or
(ii) where a previous claim was made by him, a medical board or a medical appeal tribunal have not within the period of 3 years before the claim was made reassessed the extent of his disablement at less than 20 per cent.

Claims in respect of occupational deafness
26. Where it appears that a person who has made a claim for sickness benefit by virtue of section 50A of the Act in respect of occupational deafness—
(a) may be entitled to disablement benefit, and
(b) has not previously made a claim for disablement benefit in respect of occupational deafness or such a previous claim has been disallowed,
such a claim for sickness benefit may also be treated as a claim for disablement benefit.

Further claims in respect of occupational deafness
27. (1) In the event of disallowance of a claim for disablement benefit or sickness benefit made by virtue of section 50A of the Act in respect of occupational deafness because the claimant has failed to satisfy the minimum hearing loss requirement prescribed in column 1 of paragraph A10 of Part I of Schedule 1 hereto, disablement benefit or sickness benefit made by virtue of section 50A of the Act shall not be paid in pursuance of a further claim in respect of occupational deafness made by or on behalf of that claimant unless—
(a) it is a claim made after the expiration of 3 years from the date of a claim which was disallowed because the claimant was not suffering from occupational deafness; or
(b) it is a claim made after the expiration of 3 years from the date of a reassessment by a medical board or medical appeal tribunal of the extent of the claimant's disablement at less than 20 per cent; or
(c) if the claimant would otherwise be precluded by regulation 25(2) from making a further claim after the expiration of 3 years from the date of the disallowed claim or from the date of a reassessment by a medical board or a medical appeal tribunal of the extent of his disablement at less than 20 per cent, as the case may be, it is the first claim made since that date and within 5 years from the latest date, before the date of the claim, on which he worked in any occupation specified in column 2 of paragraph A10 of Part I of Schedule I hereto.
(2) A claim to be paid benefit by virtue of paragraph (1)(c) may be disallowed by the adjudication officer, social security appeal tribunal or Commissioner, as the case may be (hereinafter called “the determining authority”), without referring the disablement question to a medical board or medical appeal tribunal where the determining authority is satisfied from the medical evidence given on the disallowed claim that the claimant is not suffering from occupational deafness.

31. Subject to the provisions of regulation 30 and notwithstanding the provisions of section 110(5) (leave of medical appeal tribunal required to review assessment in certain cases), a life assessment in respect of occupational deafness made by a medical board or a medical appeal tribunal shall not be reviewed in accordance with section 110(2) (review of assessment in case of unforeseen aggravation) without leave of a medical appeal tribunal, and in the case of a provisional assessment in respect of occupational deafness no such leave shall be required.

No appeal against initial provisional assessment of disablement in respect of occupational deafness
32. Notwithstanding section 109(2), but subject to the provisions of section 109(3), no appeal shall lie against an initial provisional assessment of the extent of disablement in respect of occupational deafness.

Cases in which reassessment of disablement in respect of occupational deafness is final

Assessment of extent of disablement and rate of disablement benefit payable in respect of occupational deafness
34. (1) Subject to the provisions of Schedule 8 and regulations made thereunder and the following provisions of this regulation, the first assessment of the extent of disablement in respect of occupational deafness made in pursuance of a claim made before 3rd September 1979 by a person to whom disablement benefit in respect of occupational deafness is payable for a period before 3rd September 1979 shall be the percentage calculated by applying the formula set out in Part III of Schedule 3 hereto to the percentages specified in column 2 of Part I of that Schedule opposite the appropriate amount of hearing loss in the better ear and the worse ear respectively specified in column 1 of that Schedule, being the total hearing loss due to all causes, measured in each case by pure tone audiometry over the 1, 2 and 3 kHz frequencies.
(2) Except in any case to which paragraph (1) applies and subject to the provisions of Schedule 8 and regulations made thereunder and the following provisions of this regulation, the extent of disablement in respect of occupational deafness shall be assessed at the percentage calculated by applying the formula set out in Part III of Schedule 3 hereto to the percentages specified in column 2 of Part II of that Schedule opposite the appropriate amount of hearing loss in the better ear and the worse ear respectively specified in column 1 of that Schedule, being the total hearing loss due to all causes, measured in each case by pure tone audiometry over the 1, 2 and 3 kHz frequencies.
(3) In this regulation and in Schedule 3 hereto “better ear” means that ear in which the claimant's hearing loss due to all causes is the less and “worse ear” means that ear in which the claimant's hearing loss due to all causes is the more.
(4) The extent of disablement in respect of occupational deafness may be subject to such increase or reduction of the degree of disablement as may be reasonable in the circumstances of the case where, having regard to the provisions of Schedule 8 and to regulations made thereunder, that degree of disablement does not provide a reasonable assessment of the extent of disability resulting from the relevant loss of faculty.
(5) Where on reassessment of the extent of disability in respect of occupational deafness the sensorineural hearing loss is less than 50dB in each ear, being due in the case of at least one ear to occupational noise, the extent of disablement shall be assessed at less than 20 per cent.
(6) Where the extent of disablement is reassessed at less than 20 per cent disablement benefit shall not be payable.
(7) In the case of a person to whom disablement benefit by reason of occupational deafness was payable in respect of a period before 3rd September 1979—
(a) if no assessment of the extent of his disability has been made, reviewed or varied on or after that date, the rate of any disablement benefit payable to him shall be the rate payable for the degree of disablement assessed in accordance with paragraph (1), but
(b) if such an assessment has been made, reviewed or varied in respect of a period commencing on or after that date and before 3rd October 1983, the rate of any disablement benefit payable to him shall be either—
(i) the rate which would by payable if an assessment were made in accordance with paragraph (2), or
(ii) the rate which was payable immediately before the first occasion on which such review or variation took place,
whichever is the more favourable to him.
(8) Where in the case of a person to whom disablement benefit by reason of occupational deafness was payable in respect of a period before 3rd September 1979 the extent of his disability is reassessed and the period taken into account on reassessment begins on or after 3rd October 1983 and—
(a) immediately before that date, by virtue of paragraph (7) the rate at which disablement benefit was payable to him was higher than the rate which would otherwise have been payable, or,
(b) the reassessment is the first reassessment for a period commencing after 3rd September 1979,
the rate of disablement benefit payable to him shall be whichever of the rates specified in paragraph (9) is applicable.
(9) The rate of disablement benefit payable in the case of a person to whom paragraph (8) applies shall be—
(a) if the current rate appropriate to the extent of his disability as reassessed is the same as or more than the rate at which disablement benefit was payable immediately before the beginning of the period taken into account on reassessment, the current rate, or
(b) if the current rate is less than the rate at which disablement benefit was payable immediately before the beginning of the period taken into account on reassessment, the lower of the following rates—
(i) the rate at which benefit would have been payable if the reassessment of the extent of his disability had been made in accordance with paragraph (1), or
(ii) the rate at which benefit was payable immediately before the beginning of the period taken into account on reassessment.

Commencement date of period of assessment in respect of occupational deafness

EXPLANATORY NOTE
These regulations are made for the purpose only of consolidating the Social Security (Industrial Injuries) (Prescribed Diseases) Regulations 1980 and subsequent amending regulations, all of which are revoked. Paragraph 12 of Part II of Schedule 16 to the Social Security Act 1975 exempts such regulations from reference to the Industrial Injuries Advisory Council and they have not been so referred.
One major difference between these regulations and those made in 1980 is that the provisions in Part V of the 1980 regulations (Procedure for Determination of Claims and Questions) are now in Part IX of the Social Security (Adjudication) Regulations 1984 and have accordingly been omitted from the present consolidation. In other respects the form and content of the present set of regulations is much as before, dealing, in the same sequence, with the prescription of diseases and presumption as to their origin (Part II and Schedule 1), the date of onset and recrudescence of disease (Part III ), the application to prescribed diseases of certain provisions of the Social Security Act 1975 and regulations made under it ( Part IV and Schedule 2), the special provisions made in respect of pneumoconiosis, byssinosis, occupational deafness and certain other diseases (Part V and Schedule 3), certain transitional provisions (Part VI and Schedules 4 and 5) and the revocation of the regulations mentioned in Schedule 6.
