法律案件

The Whistleblower Protection Enhancement Act was introduced in 2009 by Senator Daniel Akaka (D-Hawaii) to amend federal personnel law relating to whistleblower protections to provide that such protections shall apply to a disclosure of any violation of law, except for an alleged violation that is a minor, inadvertent violation that occurs during the conscientious carrying out of official duties.[2] Senator Akaka has introduced similar bills in the 107th, 108th, 109th, and 110th Congresses and every effort to pass the law has failed. Although a stronger version of the bill had been introduced and twice passed the House of Representatives (see H.R. 985 introduced in the 110th Congress and H.R. 1507 in the 111th Congress), the Senate repeatedly refused to adopt the stronger House version. During the 2008 presidential, campaign several candidates, including then-Senator Barack Obama, pledged to support the stronger House version of the bill (H.R. 985) if elected president.

In July 2009, Senator Akaka proposed a controversial amendment to S. 372 that further weakened the bill and contained several provisions that were insisted upon by the powerful federal agency managers lobby and the Obama administration. Despite campaign promises to support the stronger House bill, after the election, President Obama disappointed many when his administration actively supported the weaker Senate bill and Obama administration officials helped craft some of the controversial provisions contained in the Senate mark-up version of the bill in 2009. The Senate sponsors of S. 372 delayed presenting the controversial bill for full Senate approval until the latter stage of the lame-duck session of the 111th Congress. The Senate version of the WPEA contained only modest reforms of whistleblower rights and actually contained a few provisions that would have made it more difficult for federal employees to bring whistleblower claims. The Senate bill differed substantially from the House version and the delay tactics by the Senate sponsors of S. 372 ensured that the House was given only a take-it-or-leave-it option to take up the weak Senate bill. When the House finally considered the weaker Senate bill on the last day of the 111th Congress, the bill's sponsors needed a two-thirds vote to pass the bill on the House suspension calendar. Lacking the votes necessary to pass the weaker Senate bill, and to avoid objections raised by Republicans to the intelligence agency protections, the House sponsors of the Senate bill stripped out all protections for intelligence agency and FBI employees. The severely watered-down version of the WPEA was killed in the Senate on December 22, 2010, when a senator placed an anonymous hold on the bill.

On the Media and the Government Accountability Project have organized a grassroots effort using the Internet to attempt to determine which senator placed the anonymous hold.[3] As of March 14, 2011 (2011 -03-14)[update], only three senators had not denied placing the anonymous hold: Jon Kyl (R-AZ), Jeff Sessions (R-AL), and Jim Risch (R-ID).
