IN farther pursuance of this principle, the law also determines that in the king can be no negligence, or _laches_, and therefore no delay will bar his right. _Nullum tempus occurrit regi_ is the standing maxim upon all occasions: for the law intends that the king is always busied for the public good, and therefore has not leisure to assert his right within the times limited to subjects[u]. In the king also can be no stain or corruption of blood: for if the heir to the crown were attainted of treason or felony, and afterwards the crown should descend to him, this would purge the attainder _ipso facto_[w]. And therefore when Henry VII, who as earl of Richmond stood attainted, came to the crown, it was not thought necessary to pass an act of parliament to reverse this attainder; because, as lord Bacon in his history of that prince informs us, it was agreed that the assumption of the crown had at once purged all attainders. Neither can the king in judgment of law, as king, ever be a minor or under age; and therefore his royal grants and assents to acts of parliament are good, though he has not in his natural capacity attained the legal age of twenty one[x]. By a statute indeed, 28 Hen. VIII. c. 17. power was given to future kings to rescind and revoke all acts of parliament that should be made while they were under the age of twenty four: but this was repealed by the statute 1 Edw. VI. c. 11. so far as related to that prince; and both statutes are declared to be determined by 24 Geo. II. c. 24. It hath also been usually thought prudent, when the heir apparent has been very young, to appoint a protector, guardian, or regent, for a limited time: but the very necessity of such extraordinary provision is sufficient to demonstrate the truth of that maxim of the common law, that in the king is no minority; and therefore he hath no legal guardian[y].
