Roberts v. the Future

Since his appointment, what have been the decisions of Justice Roberts on the following legal issues?

•Drug legalization:
On January 17, 2006, he dissented alongside Justices Scalia and Thomas (the most conservative Justices) in Gonzales v. Oregon. In this case, the USSC decided that the Controlled Substances Act (regulation of drugs according to a classification from the most harmful to the least dangerous) did not allow the US Attorney General to prevent GPs from prescribing drugs for the assisted suicide of the terminally ill, in accordance with an Oregon law.

•Abortion: (a constitutional right since Row v. Wade, 1973)
Gonzales v. Carhart, 2007: he was part of the majority to uphold the constitutionality of the Partial-Birth Abortion Act 2003. The latter does not prohibit abortion, but special method of abortion used in a few weeks before the birth.
→“Ethical and moral concerns, including an interest in fetal life, represent "substantial" state interests.”

•Affirmative Action:
= a discriminatory policy, in contradiction with the equal protection clause of the 14th amendment. In Parents Involved in Community Schools v. Seattle School District No. 1, 2007: Selection based on race is constitutional as long as measures are narrowly tailored and justified by a compelling governmental interest. The first condition was not respected. Roberts: "the way to stop discrimination on the basis of race is to stop discriminating on the basis of race."

•Civil liberties:
In Jones v. Flowers, 2006: he did not agree with Antonin Scalia and Clarence Thomas in this case, and considered that before taking the seizure of a house to sell it in order to reimburse debts of the owner, the competent authority must notice the seizure to the latter.

As a conclusion: Yes Justice Roberts is quite conservative but may be sometimes liberal, on civil liberties and health issues for instance.
