I'm so happy that on one day, one judge was able to make a decision that wasn't based on his/her politcal ideology. This is supposed to be how the system works. I know that liberals have also won key battles through unelected courts as well. Law is supposed to be made by elected officials.
Actually from what I've read in the opinion so far, it is very much about Robert's ideology. At his confirmation he stressed judicial restraint and opposed judicial activism. The opinion reflects that view in deferring to the legislature where he could.
Well, it is how judges should do. Judgements must be done using laws, not ideology.
