Different institutional arrangements often lead to varying relationships between the Executive and the Legislature over the course of the budget cycle. In parliamentary systems the ruling political party often has a majority in the legislature, making the budget process more streamlined. Countries following the congressional system experience a more contentious relationship between the Executive and the Legislature, often causing delays in budget approval.

CABRI hosted a Policy Dialogue on the Role of Legislatures in the Budget Process, especially how Legislators contribute to improving budget planning and formulation, and the implementation of spending plans and oversight.
