Harry Stone never spoke of ever having kids or a family, and yet he apparently had a daughter (who if the same age as Melissa Rauch, would've been at least 4 years old at the start of the series) who followed in his footsteps for the reboot.
Harry frequently threatens people with "contempt of court" outside the courtroom environment, so therefore would be illegal. Contempt citations are only issued when a lawful order is ignored, someone shows disrespect to the judge during a session, or they disrupt the proceedings.
Dan Fielding's sexual innuendo and unwanted advances, while amusing, would be regarded as being sexual harassment. It would have cost him his job or at the very least forced his removal from the "Night Court" work lineup.
Harry Stone's romantic affairs with subordinates, while central to the show, were inappropriate even for the 1980s setting of the series. They would have had to end or Harry would have been removed from his role as a judge.
In the cafeteria, the exit doors are labeled with "These Doors Must Remain Unlocked During Business Hours". This is a California State requirement (where the series is shot), and is not seen in New York (where the series is set).
