In the case where Part II (Special Treatment Premises) of the M1London Local Authorities Act 1991 (in this section referred to as “the Act of 1991”) applies to a participating borough on the date on which this Act is passed this section shall come into operation at the end of the period of three months beginning with that date and where Part II of the Act of 1991 does not so apply shall come into operation on the date from which it first applies to a participating borough.

After the expiry of the period of four weeks beginning with the date this section comes into force in a borough, subsection (3) of section 16 (Application to existing special treatment premises) of the Act of 1991 ceases to have effect in that borough and where premises to which subsection (1) of that section does not apply are lawfully being used as an establishment for special treatment, section 6 (Licensing under Part II) of the Act of 1991 has effect in relation to those premises.

Where premises to which subsection (1) of the said section 16 does not apply are lawfully being used as an establishment for special treatment on the date this section comes into force in the borough in which the premises are situated and application for a licence under Part II of the Act of 1991 is made within four weeks of that date those premises may lawfully continue to be used as an establishment for special treatment until the determination or withdrawal of that application and if an appeal is lodged until the determination or abandonment of the appeal.
