Foreign investors, key behind Indian stocks hitting record high in March, are most concerned about the fate of national tax and land acquisition reforms in the upcoming session of Parliament.
The government, despite fierce opposition, has not given up on making it easier to acquire land needed to kick-start hundreds of billions of dollars in stalled projects, but after failing to win support in parliament may ask states to pass their own laws.
Stock falls also tracked the losses of Asian markets, where the dollar held firm as investors looked ahead to higher interest rates from the Federal Reserve, while gold slumped to five-year lows.
"Unless there is clarity on reform proposals investors are not keen to pump in new money," said Deven Choksey, managing director at KR Choksey Securities.
The BSE Sensex was down 0.41 per cent while the Nifty lost 0.47 per cent, slipping below the 8,600 mark.

ACC Ltd fell 2.9 per cent after its quarterly consolidated profit saw an about 45 per cent decline.
