Writ of Cert (Rule of 4)

Not to keep harping on the two gay marriage cases, but this is a telling article arguing that Hollingsworth v. Perry was actually a ploy by the four most conservative justices to take the case knowing that if they took the case now and it lost (and Kennedy certainly seems to be against it) that it would take years to get another likely case to the court.  The article discusses key concepts for government, noticeably the rule of four and a writ of certiorari.
