USCA Case #14-5004 Document #1570210 Filed: 08/28/2015 4 collecting plaintiffs’ call records, but stayed its order pending appeal. Klayman v. Obama, 957 F. Supp. 2d 1, 44-45 (2013). The court reverses the judgment of the district court, and for the reasons stated in the opinions of Judge Brown and Judge Williams orders the case remanded to the district court. (Judge Sentelle dissents from the order of remand and would order the case dismissed.) The opinions of the judges appear below after a brief explanation of why the case is not moot. * * * Under a “sunset” clause, the section of the U.S. Code amended by Section 215 was scheduled to revert to its pre2001 form on June 1, 2015 unless Congress acted. See Pub. L. No. 109-177, § 102(b)(1), 120 Stat. 192, 194-95 (2006); Pub. L. No. 112-14, § 2(a), 125 Stat. 216, 216 (2011). That date came and went without any legislative action. One day after the deadline, however, Congress enacted the USA Freedom Act, which revived the language added by Section 215 with some substantial changes. See Pub. L. No. 114-23, Tit. I, 129 Stat. 268, 269-77 (2015), codified at 50 U.S.C. § 1861. The Act’s changes do not take effect until 180 days after the date of enactment (June 2, 2015). Id. § 109(a), 129 Stat. at 276. And the legislation provides for continuation of pre-existing authority until the effective date of the new legislation: “Nothing in this Act shall be construed to alter or eliminate the authority of the Government to obtain an order under title V of the Foreign Intelligence Surveillance Act of 1978 (50 U.S.C. 1861 et seq.) as in effect prior to the effective date . . . during the period ending on such effective date.” Id. § 109(b), 129 Stat. at 276. Cessation of a challenged practice moots a case only if “there is no reasonable expectation . . . that the alleged violation will recur.” Larsen v. U.S. Navy, 525 F.3d 1, 4 Page 4 of 21
