The Idaho Rules of Professional Conduct (IRPC) became effective on November 1, 1986, (with subsequent amendments) by order of the Idaho Supreme Court. The IRPC are based largely on the ABA Model Rules of Professional Conduct, with some Idaho variations.
In 2003, the E2K Committee was appointed by the Idaho State Bar Board of Commissioners to review the IRPC in conjunction with the ABA’s revision of the Model Rules based upon the ABA Ethics 2000 Commission’s review and recommendations. The IRPC were thereafter revised and adopted by the Idaho Supreme Court, effective July 1, 2004. The Idaho Supreme Court also specifically adopted the comments to the IRPC. The Court has adopted amendments to a number of the rules since 2004.
