the United States attorney general to prohibit physicians from prescribing drugs for the assisted suicide of the terminally ill as permitted by an Oregon law. The point of contention in the case was largely one of statutory interpretation, not federalism. On March 6, 2006, Roberts wrote the unanimous decision in Rumsfeld v. Forum for Academic and Institutional Rights that colleges accepting federal money must allow military recruiters on campus, despite university objections to the Clinton Administration-initiated "don't ask, don't tell" policy. Campaign finance Following his concurrence in Citizens United v. FEC (2010), Roberts wrote the majority decision for another landmark campaign finance case called McCutcheon v. FEC (2014). In McCutcheon the Court ruled that "aggregate limits" on the combined amount a donor could give to various federal candidates or party committees violated the First Amendment. Fourth Amendment Roberts wrote his first dissent in Georgia v. Randolph (2006). The majority's decision prohibited police from searching a home if both occupants are present but one objected and the other consented. Roberts criticized the majority opinion as inconsistent with prior case law and for partly basing its reasoning on its perception of social custom. He said the social expectation test was flawed because the Fourth Amendment protects a legitimate expectation of privacy, not social expectations. In Utah v. Strieff (2016), Roberts joined the majority in ruling (5–3) that a person with an outstanding warrant may be arrested and searched, and that any evidence discovered based on that search is admissible in court; the majority opinion held that this remains true even when police act unlawfully by stopping a person without reasonable suspicion, before learning of the existence of the outstanding warrant. In Carpenter v. United States, a landmark decision involving privacy of cellular phone data, Roberts wrote the majority opinion in a 5–4 ruling that searches of cellular phone data generally require a warrant. Notice and opportunity to be heard Although Roberts has often sided with Scalia and Thomas, he also provided a crucial vote against their mutual position in Jones v. Flowers, siding with liberal justices of the court in ruling that, before a home is seized and sold in a tax-forfeiture sale, due diligence must be demonstrated and proper notification needs to be sent to the owners. Dissenting justices were Anthony Kennedy, Antonin Scalia and Clarence Thomas, while Roberts's opinion was joined by David Souter, Stephen Breyer, John Paul Stevens and
