The House ethics committee determined that Rep. Richard H. Stallings (D-Idaho) violated House rules governing the use of campaign funds but recommended against disciplinary action, the panel's chairman said in a letter released yesterday.

The Committee on Standards of Official Conduct investigated Stallings after complaints by the National Republican Congressional Committee that he borrowed $4,800 from his campaign to buy a car and borrowed $1,000 to lend to an aide.

Committee Chairman Julian C. Dixon (D-Calif.) said in a letter to Stallings that the loans were in violation of House rules, as Stallings has acknowledged, but the committee concluded that the violation was the result of a misunderstanding of the rules.

"Notwithstanding the violation, the committee did conclude that the transactions arose out of your mistaken impression that the loans were solely governed by the Federal Election Campaign Act," the letter said.

In addition, "there was no intent on your part to avoid public disclosure of the loans -- they were fully reported on your FEC {Federal Election Commission} reports," Dixon said.

The committee decided "the factors in mitigation are sufficient to avoid a recommendation that further disciplinary action be taken," Dixon said, but he added, "Members have the duty and responsibility to be aware of relevant House rules."
