Four Republican candidates were said to have applied to succeed Judge Charles H. Toliver IV on the state Superior Court, according to sources familiar with the process.

The candidates for the vacancy were said to be Richard A. Forsten, a partner at Saul Ewing; Ferris Wharton of the New Castle County Public Defender’s Office; Nancy Chrissinger Cobb, an attorney with her own practice; and Jennifer-Kate M. Aaronson, who heads Delaware’s Office of Disciplinary Counsel. Aaronson was viewed as a surprise candidate and she had not been speculated as applying for the position until earlier last week.

All applications were due Friday to Judicial Nominating Commission Chair William B. Chandler III and interviews are expected to occur as early as this week.

Toliver’s term expired earlier this month, but he has stayed on the bench to help ease the transition.
