In the run-up to the March 28 oral argument in the Prop 8 and Defense of Marriage Act (DOMA) cases, read what Attorney General Schuette says in Michigan's amicus briefs. Prop 8 brief: PDF. DOMA brief, (joined Indiana's lead, with 14 other states): PDF.
Here's what SCOTUSBlog has to say about all the briefs filed:
The briefs contain many things of interest. Perhaps the single most important feature of the topside amicus briefs, however, is a dog that didn’t bark — or not as loudly as might have been expected, in any event.
Forty-one states prohibit same-sex marriage. But only twenty of those forty-one states have filed briefs in support of the constitutionality of Proposition 8: Indiana is the lead party on a brief for nineteen states, and Michigan filed a brief of its own. Compare this level of state participation with, for example, the amicus brief filed by all forty-nine other states in Maryland v. King (to be argued February 26), in support of Maryland’s argument that a state does not violate the Fourth Amendment by collecting and analyzing the DNA of persons who have been arrested for, but not convicted of, a criminal offense.
