In the structure of governance, the Legislature plays a key role.
Representation, legislation, supervision, and examination are some of its main responsibilities.

Legislators who do their jobs well transform public opinion into policy (law) and keep a close eye on executive actions to make sure they are carried out ethically, effectively, and in line with legislative purpose.

The budget process, which involves passing the yearly budget and monitoring government expenditures, is a key component of parliamentary supervision and NABRO plays vital role in the appropriation review process.

An Appropriation Act is a proposed law that authorizes the expenditure of government funds. It is a bill that authorises amounts to be issued from the public accounts and applied for services in a financial year.
