On Wednesday the Washington Post published an article, Judges Should Have ’Limited’ Role, Roberts Says, that quotes from the questionnaire Judge Roberts answered for the Senate Judiciary Committee. Regarding judicial activism, Roberts wrote:
"When the other branches of government exceed their constitutionally-mandated limits, the courts can act to confine them to the proper bounds. It is judicial self-restraint, however, that confines judges to their proper constitutional responsibilities."
The article also includes a sidebar that gives an on-line, PDF copy (in 3 parts) of the completed 76-page questionnaire and financial disclosure Roberts submitted to the Committee. It includes a paragraph about his involvement with the Federalist Society, where he acknowledges participating in their events (between 1993 and 2003) but has no recollection of serving on any of their committees or ever being a member.
Part 3 of the questionnaire also includes his description of the selection process he went through (e.g., first interviewed on April 1, so and so was present, no I was never asked how I would rule on a given case or issue) and his view of judicial activism.
