Thirlage Act 1799

10 Commutation shall not give claim to the mill proprietor to relief from the land tax, nor affect right of freehold. E+W+S

And whereas the annual payment to be adjudged under this Act to the proprietor of a mill in lieu of the multures, mill services and other rights from which the lands thirled are to be thereby relieved, is meant and understood to be of equal value and a full compensation for the discharge thereof, and in no ways to take from or diminish the value of his right as proprietor: It is further hereby enacted and declared, that the discharge of the multures, mill services and other rights belonging to a proprietor of a mill, as to the whole or any part of the lands astricted to it, and the substitution of an annual payment by way of compensation in place thereof in the manner above provided for, shall afford to such proprietor no ground or pretence for claiming relief from any part of the cess or land tax payable by him in respect thereof, either where such mill stood separately valued in the cess books or where it was included in a joint or cumulo valuation with other parts of his property; and for the same reason, that it shall not in anyways affect or impair any right of freehold or qualification to elect or be elected as a member of Parliament arising from or founded upon it, either where the mill with its mill lands and multures of itself affords such qualification in respect of its valuation or old extent or where it makes part of a tenement which forms such qualification either on its valuation or as separately retoured of an extent sufficient for that purpose.
