The Supreme Court on Monday questioned the Enforcement Directorate's conduct in politically sensitive cases as it upheld the Karnataka High Court's decision to quash the case against Chief Minister Siddaramaiah's wife in the MUDA case.

Cautioning against the agency being used as a tool in political battles, a bench comprising Chief Justice B R Gavai said, "Let political battles be fought before the electorate. Why are you being used?".

The bench comprising Chief Justice Gavai and Justice K Vinod Chandran was hearing the ED's appeal challenging a Karnataka High Court order that quashed proceedings in the Mysuru Urban Development Authority (MUDA) case involving BM Parvati, wife of the Karnataka chief minister.
