TAKING a cue from the Supreme Court, the Election Commission has been sending shockwaves through political parties. Last week, Election Commissioner G.V.G. Krishnamurthy raked up an issue that T.N. Seshan had earlier taken up and apparently abandoned. While the apex court recently asked political parties to regularly file their income-tax returns, Krishnamurthy opined that political parties should exercise inner-party democracy, including holding elections with regular intervals as per the provisions of the Peoples' Representation Act, under which they are registered with the Commission. His order requires parties to furnish the political principles, policies, aims and objectives besides names of those holding important office as per the party constitution. Last year, Seshan had suggested restoration of internal democracy, including elections, by the end of 1995.
