'Constitutional Conundrum: What if PM is removed by a 51% vote in Lok Sabha?'

Imagine Modi ji is PM but Lok Sabha has a hung assembly, and no party has a majority. In this scenario, someone files a PIL that the PM can be removed by a simple 51% vote in Lok Sabha, citing the 'public interest'. The argument goes that with a hung parliament, the PM is unable to effectively govern and thus the Lok Sabha should have the power to remove them. What would be the Constitutional outcome? Would this go against the principles of parliamentary democracy or would it be interpreted as a necessary evil in times of national crisis? Jab tum log mock tests dete ho, I'm at my shift
