He served as a Second Lieutenant in the United States Army immediately after World War II, from 1946 to 1947.
[2] In 1986 Catholic University in Washington, D.C. published a law review article authored by Pieras regarding the technique he had implemented in his courtroom through a standing order in all his civil cases which he appropriately had named the “Initial Scheduling Conference” or “ISC” for short.
In his law review article, Pieras advocated that the ISC be incorporated in the Federal Rules of Civil Procedure.
Shortly after the article's publication, President Joe Biden (at the time, Senator Joseph Biden, (D.) Delaware, then Chairperson of the Senate Judiciary Committee) personally called Judge Pieras to let him know that he had read his article and that not only had he liked it but that he was taking it very seriously and was intent on amending the Rules of Civil Procedure to include the Initial Scheduling Conference as a mandatory proceeding in federal courts, the reason for which he was creating an advisory committee and that he wanted him to be a member.
Pieras, as a life-long Republican, a former Republican National Committeeman and a Reagan appointee to the bench, hesitated for a few seconds regarding Sen. Biden's invitation to participate in a committee chaired by a Democrat, but he quickly put political convictions aside and graciously accepted to participate in the actual writing of the amendments of the Rules of Civil Procedure which would incorporate his inspiration.
