Catherine's ringtone is the theme song to "The Practice," the predecessor to "Boston Legal."
Alan Ruck costarred with William Shatner in Star Trek Generations.

Denny calls Valerie Bertinelli by her name twice, rather than her character's name (Carol or Ms. Hober) at the conclusion of the hearing.
As Alan and Carol Hober, and finally Denny, leave Alan's office at the beginning of the episode, the song "One Day at a Time" is played, a clear reference to Valerie Bertinelli, who plays Carol, and her stint on "On Day at a Time," the sit-com that ran from 1975 to 1984 that she starred in. That song was the theme song of that show.
While defending Alan, Melvin Palmer tells the Utah judge about Alan "taking on the supreme court" and "winning the case". Alan argued before the supreme court in season four but the outcome was not revealed. This confirms that Alan won that Supreme Court case.
It appears that Alan Shore lives in Room 416, since it is the number that can be seen on the door to his hotel room.

Alan and Denny's conversation on the balcony at the end of the episode, prefigures a lot of the events of the series finale:

Denny Fishing for sure.
Alan For sure.
Denny Supreme Court, gotta go back.
Alan Scalia misses me.
Denny Of all the women I have loved, and been loved by, whoever would have believed that Alan Shore would be my prince charming.

(Following a return visit to the Supreme Court, Alan and Denny go to Nimmo Bay and are married, according to Massachusetts law, by Justice Scalia.)
