1911 Encyclopædia Britannica/Preamble
PREAMBLE (Med. Lat. praeambulum, from praeambulare, to walk before), an introductory statement, a preliminary explanation. The term is particularly applied to the opening paragraph of a statute which summarizes the intention of the legislature in passing the measure; thus the preamble of the statute, of which the title is the Children Act 1908, is as follows: “ An Act to consolidate and amend the Law relating to the Protection of Children and Young Persons, Reformatory and Industrial Schools and Juvenile Offenders, and otherwise to amend the Law with respect to Children and Young Persons.” The procedure in the British parliament differs in regard to the preambles of public and private bills. The second reading of a public bill affirms the principle, and therefore in committee the preamble stands postponed till after the consideration of the clauses, when it is considered in reference to those clauses as amended and altered if need be (Standing Order 35). On the other hand, the preamble of a private bill, if opposed, is considered first in committee, and counsel for the bill deals with the expediency of the bill, calls witnesses for the allegation in the preamble, and petitions against the bill are then heard; if the preamble is negatived the bill is dropped, if affirmed it is gone through clause by clause. On unopposed private bills the preamble has also to be proved, more especially with regard to whether the clauses required by the standing orders are inserted (see May, Parliamentary Practice, 1906, pp. 483, 808 seq.).
