CARSON CITY -- The Nevada Supreme Court added a new rule to its code of judicial conduct on Friday to require judges to disclose past relationships with attorneys who worked for them as law clerks.

It also adopted a rule allowing the peremptory challenges of senior judges in some cases.

The disclosure rule, one of several proposed by retiring Chief Justice Bob Rose, will require judges to disclose law clerk relationships within three years of their employment. An opposing attorney appearing before the judge would then have the opportunity to ask the judge to disqualify himself based on the relationship.

"A party or the party's lawyer might reasonably consider another attorney's recent service to the judge as a former law clerk to be a relationship relevant to the question of disqualification," the new rule states in part.

The change to the challenge of senior judges allows for removal if there are at least 30 days before a motion is to be considered or a trial is to get under way. No challenges will be allowed if a senior judge is assigned to a matter with fewer than 30 days before a case is to be considered.

The rules, along with others still being considered by the court, were proposed following a series of articles by the Los Angeles Times about the Nevada judiciary.

Another court change still under consideration by the court would require disclosure by a judge when a person or entity appearing in a court case has contributed more than $10,000 to the judge's re-election campaign.
