Do you think the majority in Dickerson VS. The United States engaged n judicial activism? Why or why not?

Question

Can someone help me understand the difference between judicial activism and judicial restraint? Also I need to find a little more info on this case to help me write this essay.

I'll let you read these sites about the case and the differences between judicial activism and restraint and make your own decision.

Also note this quote from the site linked below. Apparently experts can't agree on this subject.

"It's hard to see Dickerson as an activist decision: The court adhered to precedent and confirmed that a law long thought to be unconstitutional was in fact invalid. However, critics include Dickerson in the list of cases that are supposed to prove the court's conservative activism."
