Congress often attaches limitation riders to appropriations bills to establish its policy directives. Professor Devins argues that the appropriations process is not the proper vehicle for substantive policymaking. In this article, he analyzes institutional characteristics that prevent the full consideration or articulation of policy in appropriations bills. Professor Devins also considers the extent to which Congress's use of limitation riders inhibits the effectiveness of the other branches of the federal government. Professor Devins concludes that, while Congress's use of limitation riders is sometimes necessary, Congress should be aware of the significant risks associated with policymaking through the appropriations process.
