Is the public allowed to see the Supreme Court in action during cases? Like, could an average Joe walk into the Supreme Court building, listen to the justices hear and judge a case, and walk out once it's wrapped up?

Yes but for high profile cases you'll have to line up before the court opens in order to guarantee a seat. It's first come, first serve.

You absolutely can, though, depending on the cases being heard on any given day, you may have to line up early to get in.

You would have to get permission ahead of time.
