For those who are wondering about the setting for Intergalactic Law, the ship, The Isaac Newton, is inspired by Arthur C Clarke's Rama. Rendevouz with Rama was one of the first sci-fi books I read. I was pretty young at the time, and I don't know if the story made much of an impression on me, but the setting of a giant cylindrical ship certainly did.
Below is a fantastic image inspired by Rama, and is very close to what I picture the interior of the Isaac Newton to be like.
