A South Dakota judge has issued a preliminary injunction on Initiated Measure 22. Initiated Measure 22 was approved by the majority of South Dakota voters last month as an act to revise campaign finance and lobbying laws.

The injunction will give the courts and the Legislature time to consider the measure, which has been widely criticized as being poorly drafted and possibly unconstitutional. Supporters of Initiated Measure 22 are expected to ask the judge to re-instate portions of the law not challenged by the plaintiffs, such as the provisions dealing with lower caps on campaign contributions.
