New Jersey Supreme Court Justice Roberto Rivera-Soto admitted on Friday that he created an appearance of impropriety by contacting school, police and court authorities in a dispute involving his son, but denied any deliberate misconduct.

In a letter to the Advisory Committee on Judicial Conduct, he said that in order to “prevent any further harm to the court’s reputation” he would waive a formal hearing and stipulate that the charges against him be decided on the basis of the investigatory record and his statement in lieu of formal testimony.
