[JURIST] The US Court of Appeals for the Ninth Circuit [official website] heard arguments Wednesday regarding the constitutionality of a voter-approved California law [Proposition 69, PDF] that requires police officers to take DNA samples of arrested persons suspected of committing a felony. Sitting en banc, the judges questioned California Attorney General Kamala Harris [official website], raising concerns [San Francisco Chronicle report] that the law may be an unconstitutional government invasion of individuals' privacy. Harris retorted that the law contains safeguards against malicious use, including penalties for state officials who misuse DNA material. In February a three-judge panel of the Ninth Circuit ruled [opinion, PDF; JURIST report] that Proposition 69 does not violate Fourth Amendment [LII backgrounder] protections against unlawful searches and seizures. It is not yet clear when the full Ninth Circuit will issue a new ruling in the case, entitled Haskell v. Harris [materials]. The California Supreme Court [official website] is currently reviewing Proposition 69 in a separate case.

US Attorney General Eric Holder instructed federal prosecutors in November 2010 to use DNA evidence as much as possible [JURIST report] reversing the previous policy of the Bush administration. In May 2009 a federal court in California upheld the constitutionality of mandatory DNA collection [JURIST report] for all persons arrested or detained under federal authority.
