Ch.XVI. Sec.L] Crown Grants. 385 nizens (a). Nor can the King grant a trust reposed in himself as sovereign, as a lapse {b). Nor could he grant his dispensing power (c) ; or purveyance ; butlerage, &c. {d) : and he is re- strained from transferring his prerogative in saltpetre {e); the year day and waste (f) ; and the power of prosecution upon and carrying into eiFect, a penal or other statute or law (g).

And both at common law (/), and by statute (m), grants or promises of fines or forfeitures before the conviction of, or judgment against, the party on whom they are to be levied, are void. Nor can the King by grant create a forfeiture of goods, &c. On this ground the charter of Hen. 6. to the corporation of dyers within London, granting them power to search, &c. and if they found any cloth dyed with logwood, that the cloth should be forfeited, was held void (n).

Therefore grants by the King that a merchant shall pay so much for searching or measuring his goods (p) ; that he shall not import wine without paying sO much {q) ; that a merchant who imports wine at any other port (a) Bro.
