Lacunae Law and Legal Definition

The term lacunae means gaps, the plural form of the word lacuna. In law, the term refers to a situation where there is no applicable law. In certain situations, where there is no law governing a situation adjudicating bodies come to the conclusion that there is a lacunae in law. Mostly, such lacunas are present in international law. This is because even the International Court of Justice or other ad-hoc courts cannot invent laws to fill the gap. However, in the U.S., when a lacuna arises in an issue, courts decide on the matter where discretion is allowed by the legislature.
