 386: Croxvn Grants, [Ch.XVI. Sec.L than the port of S. shall pay treble customs {a), are respectively unfounded. And merchants are not, it seems, bound by their voluntary grant to the King of a tax on their goods ; as that would induce them to sell at higher prices (b). But in certain cases where there is a substantial quid pro quo, a real benefit to the subject of which he can and does avail himself; the King may by grant impose a reasonable charge on his subjects for a limited or other period. Therefore the King may grant a market, fair, ferry, &c. with liberty to take toll (c) : and by prescription, a subject may claim pontage, for building and keeping a bridge ; or murage, for erecting and keeping a wall for defence, &c. {d) ; or toll thorough, that is, toll for passing a highway kept in repair, &c. by the claimant, there being a good consideration and benefit moving to the subject {e). The writ of ad quod damnum {/), which is in general issued previous to the grant of a fair, &c. shews how zealously the law has con- sulted the common weal in these cases. So a grant from the Crown, in derogation of the common law, as that one should hold a court of equity, &c. (g) ; or that an estate should descend contrary to the common law, as according to the custom of gavelkind, &c. (h) ; or contravening the statute law, as the Navigation Act, &c. (/), is void; for the King cannot make law or custom by his grant. And if penalties are given by Acts of Parliament for relief of the poor, the King cannot ' dispose of them otherwise {k). It is scarcely necessary to mention that the King's grant$ are invalid, when they destroy and derogate from rights pre- viously vested in another subject by grant, &c. (/). ' Having thus mentioned the principal cases in which the JCing is restrained in his grants, it will naturally be our nei^t subject of inquiry, in what instances no such restraint exists.
