A parliamentary committee functions in oversight by scrutinizing government actions and examining proposed legislation. These committees gather evidence, hold hearings, and analyze documents to evaluate compliance with legal and ethical standards. They play a critical role in ensuring accountability, allowing members to question government officials about policies and expenditures. Reports generated by these committees can inform public debate and influence policy changes. Furthermore, committees can investigate issues of national importance, providing recommendations that help shape legislative priorities and ensure that the government's actions align with constituents' interests.
