The original intent of Rule 83 of the Federal Rules of Civil Procedure (1983), which authorized Federal courts to promulgate local rules. Since then, the rapid proliferation of local rules has created problems in cost, delay, and injustice. Reform of local rules is required to remedy these problems while preserving flexibility and diversity. Colorado's 1982 plan to revise its local rules incorporates most of the best features of the proposals by Judge Jack B. Weinstein and administrator Steven Flanders. The plan adheres to the principle of prepromulgation publication of rules, bar imput, and uniformity. Matters of truly local concern have been left to the lcoal courts to handle. Colorado's 'practice standards' approach supplements the procedural and informational goals of the proposals: local rules are collected centrally as part of the rules of civil procedures. The plan would benefit from certain further modifictions. Local rules would be brought into conformance with the statewide practice standards. In addition, annual reviews at the state bar convention a comprehensive review by the local rules committee after the standards have been in effect for 2 years should be scheduled.
