Acts of Parliament are sometimes called ordinances; also, certain colonial laws and certain acts of Congress under Confederation; as, the ordinance of 1787 for the government of the territory of the United States northwest of the Ohio River; the colonial ordinance of 1641, or 1647. This word is often used in Scripture in the sense of a law or statute of sovereign power. Ex. xv. 25. Num. x. 8. Ezra iii. 10. Its most frequent application now in the United States is to laws and regulations of municipal corporations. Wharton (Law Dict.).
