The unicameral Parliament enacts legislation in the same manner as in other Commonwealth realms that use the Westminster system of government. The cabinet collectively agree government policy, then the relevant minister introduces bills to Parliament, depending on which government department is responsible for implementation of a particular law. Back bench members of parliament can also introduce bills. Parliament debates bills, and (section 110.1 of the Constitution) they become enacted laws when the Speaker certifies that Parliament has passed them. There is no Royal assent.
