After 21 years on the Mississippi Supreme Court and 10 years as chief justice, Bill Waller Jr. says it's time for someone else to take the helm.

Waller's court has at times questioned problems with forensic evidence, but passed when asked to rule on the legality of Mississippi's cap on punitive damages. He said his biggest regret is not getting a statewide system of county courts.

Gov. Phil Bryant has announced that he will replace Waller with Court of Appeals Chief Judge Kenny Griffis, while Presiding Justice Michael Randolph will become the next leader of the nine-member Supreme Court, based on seniority. The outgoing chief justice, son of the late Gov. Bill Waller Sr., a Democrat who served from 1972 to 1976, said he still might run for governor himself.

Waller came on to the court in a different time, before the new judicial building was started, when most record-keeping was on paper and when a hot political battle was waging over limiting damages on civil lawsuits. Another change has been improvements in how inmates are represented in appeals, with the creation of the Office of Capital Post-Conviction Counsel and then the Office of Indigent Appeals.
