Washington ? Supreme Court nominee Harriet Miers pledged unflagging opposition to abortion as a candidate for the Dallas City Council in 1989, according to documents released Tuesday. She backed a constitutional amendment to ban the procedure in most cases and promised to appear at “pro-life rallies and special events.”

Asked in a Texans United For Life questionnaire whether she would support legislation restricting abortions if the Supreme Court allowed it, Miers indicated she would. Her reply was the same when asked, “Will you oppose the use of city funds or facilities” to promote abortions?

Supporters of Miers’ nomination said they hoped the single sheet of paper – delivered to the Senate Judiciary Committee as part of a shipment of 12 boxes of documents – would help reassure rebellious conservatives that she would not disappoint them if she took a seat on the high court.

President Bush knew of the views she had held before he picked her for the court, spokesman Scott McClellan said at the White House. But he said the president “did not discuss with her or anyone else whether or not those were still her views.”

One Democratic supporter of abortion rights responded warily. “This raises very serious concerns about her ability to fairly apply the law without bias in this regard. It will be my intention to question her very carefully about these issues,” said Sen. Dianne Feinstein of California.

Miers also returned a lengthy questionnaire to the Judiciary Committee during the day in which she wrote that the “role of the judiciary in our system of government is limited. … And of course, parties should not be able to establish social policy through court action, having failed to persuade the legislative branch or the executive branch of the wisdom and correctness of their preferred course.

“Courts are to be arbiters of disputes, not policymakers.”

Bush nominated Miers three weeks ago to succeed retiring Sandra Day O’Connor, the justice who has cast the pivotal vote in a string of 5-4 rulings in recent years that sustained abortion rights, upheld affirmative action and limited the application of the death penalty. Many Republicans had hoped Bush would pick a prominent conservative with a long record on abortion and other issues rather than a 60-year-old White House counsel whose private law practice consisted almost entirely of representing corporate clients.

While the Texans United For Life questionnaire was unsigned and undated, senior Justice Department officials who briefed reporters said Miers herself had included it in material for the Judiciary Committee.
