and does not believe the 4th and 5th amendment apply to minors (that almost certainly means he would enforce parental consent laws for abortion).

The D.C. Circuit case Hedgepeth v. Washington Metro Authority, 386 F.3d 1148, involved a twelve-year-old girl who was invited to incriminate herself as an illegal drug user, taken into custody, handcuffed, driven to police headquarters, booked, and fingerprinted because she violated a publicly-advertised zero tolerance "no eating" policy in a Washington D.C. metro station by eating a single french fry. Roberts wrote for a 3-0 panel affirming a district court decision that dismissed the girl's complaint, which was predicated on the Fourth and Fifth Amendments, specifically the claim that an adult would have only received a citation for the same offense, while children must be detained until parents are notified.
Roberts began his opinion by noting, "No one is very happy about the events that led to this litigation," and pointing out that the policies under which the girl was apprehended had since been changed. Because age discrimination is allowed under previous jurisprudence if there is any rational basis for it, only weak state interests were required to justify the policy. "Because parents and guardians play an essential role in that rehabilitative process, it is reasonable for the District to seek to ensure their participation, and the method chosen — detention until the parent is notified and retrieves the child — certainly does that, in a way issuing a citation might not." Roberts concluded that the age discrimination and detention in this case were constitutional, noting that "the question before us... is not whether these policies were a bad idea, but whether they violated the Fourth and Fifth Amendments to the Constitution.", language reminiscent of Justice Potter Stewart's dissent in Griswold v. Connecticut, in which Justice Stewart wrote, "We are not asked in this case to say whether we think this law is unwise, or even asinine. We are asked to hold that it violates the United States Constitution. And that, I cannot do."
Military tribunals
In Hamdan v. Rumsfeld, Roberts was part of a unanimous panel overturning the district court ruling and upholding military tribunals set up by the Bush administration for trying terrorism suspects known as enemy combatants. Circuit Judge A. Raymond Randolph, writing for the court, ruled that Hamdan, a driver for al-Qaeda leader Osama bin Laden <27>, could be tried by a military court because
the military commission had the approval of Congress;
the Third Geneva Convention is a treaty between nations and as such it does not confer individual rights and remedies enforceable in U.S. courts;
even if the Convention could be enforced in U.S. courts, it would not be of assistance to Hamdan at the time because, for a conflict such as the war against al-Qaeda (considered by the court as a separate war from that against Afghanistan itself) that is not between two countries, it guarantees only a certain standard of judicial procedure without speaking to the jurisdiction in which the prisoner must be tried.
The court held open the possibility of judicial review of the results of the military commission after the current proceedings have ended.<28>
Environmental regulation
On the U.S. Court of Appeals, Roberts wrote a dissenting opinion regarding Rancho Viejo, LLC v. Norton, 323 F.3d 1062, a case involving the protection of a rare Californian toad under the Endangered Species Act. When the court denied a rehearing en banc, 334 F.3d 1158 (D.C. Cir. 2003), Roberts dissented, arguing that the original opinion was wrongly decided because he found it inconsistent with United States v. Lopez and United States v. Morrison in that it focused on the effects of the regulation, rather than the taking of the toads themselves, on interstate commerce. In Roberts's view, the Commerce Clause of the Constitution did not permit the government to regulate activity affecting what he called "a hapless toad" that "for reasons of its own lives its entire life in California." He said that reviewing the case could allow the court "alternative grounds for sustaining application of the Act that may be more consistent with Supreme Court precedent."
