An omission or AMBIGUITY in a legal document that allows the intent of the document to be evaded.
Loopholes come into being through the passage of statutes, the enactment of regulations, the drafting of contracts or the decisions of courts. A loophole allows an individual or group to use some gap in the restrictions or requirements of the law or contract for personal advantage without technically breaking the law or contract. In response, lawmakers and regulators work to pass reforms that will close the loophole. For example, in the federal tax code, a long-standing loophole was the socalled tax shelter, which allowed taxpayers to reduce their tax debt by making investments. Although not closed entirely, this loophole was substantially reduced by the TAX REFORM ACT OF 1986 (Pub. L. No. 99-514, 100 Stat. 2085 [codified as amended in numerous sections of 26 U.S.C.A.]).
Loopholes exist because it is impossible to foresee every circumstance or course of conduct that will arise under, or in response to, the law. Loopholes often endure for a time because they can be difficult to close. Those who benefit from a loophole will lobby legislators or regulators to leave the loophole open. In the case of ELECTION CAMPAIGN FINANCING, it is the legislators themselves who benefit. The Federal Election Campaign Act Amendments of 1974 (Pub. L. No. 93-443, 88 Stat. 1263  [codified as amended in scattered sections of 2 U.S.C.A. §§ 431–455 (1988)]) were passed to limit private financing of federal election campaigns. But loopholes in the law allow these limits to be circumvented. Through one loophole, intermediaries can pool or "bundle" contributions so that the limit is not legally exceeded. Through another, money raised specifically for building political parties (soft money) is funneled into campaigns.
