HARRISBURG — A day after being charged with a second perjury count, Pennsylvania’s attorney general said Friday she had reported a state Supreme Court justice for possible ethics violations, citing pornographic, racially offensive or otherwise inappropriate emails he received that were recovered from her office’s computer servers.

Attorney General Kathleen Kane released one of several letters she sent Wednesday about Justice Michael Eakin to various state ethics agencies, the latest development in a year-old pornographic email scandal that has spurred a wave of resignations or firings of state officials.

In the letter, Kane wrote that the emails may run afoul of rules that judges must act in a way that promotes public confidence in the judiciary and can’t take part in activities that would appear to undermine their independence, integrity and impartiality.

A state courts spokesman said Friday that it had hired a Pittsburgh law firm to look into the matter.

Eakin said in a statement issued through the courts that he would cooperate with a judicial ethics investigation, but he otherwise declined to comment.

The emails allegedly involving Eakin were among a batch the attorney general’s office said it submitted to the Pennsylvania Supreme Court last fall as the pornographic email scandal began unfolding.

However, a lawyer retained by the court to review the thousands of emails between justices and the state attorney general’s office from 2008 through 2012 reported finding no new improprieties at the time.

Eakin is one of the five justices who voted to suspend Kane’s law license.
