On October 3 1984 Kollar-Kotelly was nominated as an associate judge of the D.C. Superior Court by President Ronald Reagan; she took her oath of office on October 21. She served as Deputy Presiding Judge Criminal Division from 1997 to 1997. She was appointed as a judge to the U.S. District Court for the District of Columbia by President Bill Clinton on March 26 1997 to a seat vacated by Harold H. Greene; she took her oath of office on May 12 1997. Chief Justice William Rehnquist appointed Judge Kollar-Kotelly to serve on the Financial Disclosure Committee (200002) and later as Presiding Judge of the United States Foreign Intelligence Surveillance Court where she served from 2002 to 2009.

Judge Kollar-Kotelly received attention from a 2006 Washington Post article describing her administration of the FISC and in particular what weight evidence taken from warrantless searches should be given to issuing subsequent search warrants for suspects of terrorism and espionage.1 Notable cases

In August 2001 Kollar-Kotelly was assigned the United States v. Microsoft anti-trust case after Judge Thomas Penfield Jackson was removed from the case. The decision was reversed in part and upheld in part.

Kollar-Kotelly denied a last-minute appeal by Saddam Hussein's legal team stating that the United States has no right to interfere with the judicial processes of another nation's courts. In August 2007 she ordered the administration of George W. Bush to give its views regarding records requests by the American Civil Liberties Union on the National Security Agency's wiretapping program.2

On October 1 2007 Kollar-Kotelly reversed George W. Bush on archive secrecy in a 38-page ruling which said that the U.S. Archivist's reliance on the executive order to delay release of the papers of former presidents is "arbitrary capricious an abuse of discretion and not in accordance with law."3 The National Security Archive at George Washington University alleged that the Bush order severely slowed or prevented the release of historic presidential papers.4

On June 16 2008 Kollar-Kotelly ruled that the Office of Administration was not subject to the Freedom of Information Act and therefore did not have to release records regarding missing White House e-mails. This was seen as a victory for the Bush Administration in terms of maintaining a tight grip on the flow of information about the executive branch.5

On September 20 2008 Judge Kollar-Kotelly issued a preliminary injunction ordering Vice President of the United States Dick Cheney and the National Archives to preserve all of Cheney's official records.6 On March 19 2009 the judge issued a preliminary injunction in a joint lawsuit brought by the Brady Campaign to Prevent Gun Violence the National Parks Conservation Association and the Coalition of National Park Service Retirees to block a change of rule which had been enacted by the United States Department of the Interior after being supported by 51 members of Congress and passing an extended public comments period. Said rule change repealed restrictions on licensed concealed carry in national parks. She stated that her decision to block the change of rule was because there was no environmental analysis performed and therefore Congress "ignored (without sufficient explanation) substantial information in the administrative record concerning environmental impacts" of the rule.7 References Carol D.
