Measure gives validity to the grant.

Explanation

(English-origin maxim.) A grant must specify with certainty the quantity, bounds, or measure of what is conveyed — without definite measure, the grant is void for uncertainty. This applies equally to delegations of governmental power: authority not defined in scope and measure by the People's constitutions is authority never granted.

Where this applies

• A deed that fails to specify the acreage or boundaries of the land is void because the grant lacks the measure needed to define what is conveyed.
• A delegation of power to a government agency that does not define the scope or limits of that power is invalid because unmeasured authority was never granted by the People.
• A contract to sell timber without specifying the quantity or the area of forest is unenforceable because measure was never given to the grant.
