I want to know the answer to the following question:
In what month and year was Roper v. Simmons decided?
All the background I'm provided with is that "The Court, considering the case Roper v. Simmons in March 2005, found the execution of juvenile offenders unconstitutional by a 5–4 margin, effectively raising the minimum permissible age to 18.". Is that enough to answer the question?
