Recently the Supreme Court ruled that legislators cannot claim immunity from criminal prosecution for bribery related to their speech and votes in the House.

Doctrine of stare decisis is a legal principle that obligates judges to adhere to prior verdicts while ruling on a similar case.
Previously the legislators were immune when accepting a bribe and voting as agreed. However, if they accepted a bribe but voted independently, they could be prosecuted.
Kuldip Nayar case (2006) held that elections to the Rajya Sabha are not proceedings of the legislature but a mere exercise of franchise and therefore fall outside the ambit of parliamentary privileges under Article 194.
