In European Union law, a decision is a legal instrument which is binding upon those individuals to which it is addressed.[1] The legislative procedure for the adoption of a decision varies depending on its subject matter.Common uses of decisions involve the Commission ruling on proposed mergers, and day-to-day agricultural matters (e.g. setting standard prices for vegetables).[citation needed] On the basis of case law, decisions may have direct effect, that is to say they may be invoked by individuals before national courts.You can help Wikipedia by expanding it.This article about a constitutional law topic is a stub.
