As widely expected, Judge John Roberts held his ground Tuesday and declined to answer a range of questions put forth by members of the Senate judiciary committee.
Nominated to be the next chief justice of the United States, Roberts spent the second day of his confirmation hearings patiently deflecting questions from Senate Democrats on abortion rights, presidential powers during wartime and the scope of federal anti-discrimination statutes.
"I need to decide those questions with an open mind, on the basis of the arguments presented, on the basis of the record presented in the case and on the basis of the rule of law, including the precedents of the court," Roberts said, responding to a question from Sen. Joe Biden, D-Del.
While he steadfastly refused to offer an opinion about Roe v. Wade, the landmark 1973 Supreme Court decision establishing a constitutional protection for abortion, Roberts said there should be a high threshold for overruling court precedents.
"I do think that it is a jolt to the legal system when you overrule a precedent," he said. "Precedent plays an important role in promoting stability and evenhandedness."
Still, he left open the possibility that certain cases could be reversed, even at the expense of stability.
"There are situations when that's a price that has to be paid."
Roberts repeatedly emphasized the limited role of the judiciary, asserting that judges must simply decide the cases before them.
But from 1982 to 1986, Roberts played an active role in advocating policy in the Reagan White House.
