Correct. Please show "Cannon" that states that skipping is an IMPERIAL felony crime. Serving civil legal papers shows that it ISN'T.
I'll wait....
Expect a long wait. You may be confusing me with someone else, 'cause I don't recall saying anything about it being an Imperial felony - or a misdemeanor, for that matter.
Active Imperial involvement? Yes, though I don't think Imperial agents generally take a direct hand: I think they issue the legal authority, but you gotta go hire your own people to do the job. Until the case appears before an Imperial ... judge? magister? arbiter? ... it's a dispute between two civilians, and it could as easily be a computer error or some corrupt bank official as a failure of the ship owner, so putting Imperial officers at physical risk for the benefit of one side in a two-sided dispute is not something I'd do. Criminal matter? Not unless you're fiddling with your transponder signal or endangering traffic in your effort to avoid foreclosure.
(Sorry, I don't have Mongoose and, from what I've heard so far, probably won't get it - or at least it's well down on my priority list. It's enough trying to wrap my head around the MegaTrav and GURPS stuff with only a handful of the necessary books, and I'm thinking strongly of getting the new T5 - if I can figure out how. From where I sit, Imperial ships only get involved if there's an actual court hearing, a ruling against them, appeals are exhausted, and the players somehow manage to get back to the ship and launch despite that - which effort would involve a number of criminal violations, not the least of which would be launching in defiance of Port Authority Traffic Control instructions and thereby endangering other traffic. What can I say - I'm a bureaucrat.)
While skipping in a ship may seam more like repo of a car, plane, boat, whatever... why shouldn't defaulting on a loan have some similarities with home mortgage law, business law or other property law? Once proper action by the lender has occurred, the police help the lender recover the property by evicting the delinquent payer and everyone else so that the lender can take possession.
U.S./Terra, the police get involved after the
judge has heard the case and made a ruling, or if someone does something that makes the judge worry about the security of the property prior to the ruling. "Proper action," in this context, means the lender has appeared and argued his case, the holder/debtor has argued his case (or failed to appear and argue after receiving a proper summons to do so), the judge has weighed the arguments and has issued a finding in favor of the lender. The police are then responding to a judicial order. This would only occur after a number of intervening hurdles had been cleared.
What those hurdles are has been left - deliberately, most likely - unstated in the Traveller universe. It's up to the gamemaster to decide how generous or cruel he's feeling. You could conceivably have the player's ship locked down the first time he misses his roll. Or, you could invent bureaucratic chances for him to legally evade the "axe": the lender must first, in the presence of an official accompanying witness, physically present the debtor with a notarized demand letter demanding arrears be rectified by a set deadline; after that deadline, the lender must present a notarized notice of intent to foreclose, with a second deadline by which the debtor can avoid foreclosure by paying all arrears (and perhaps penalties); after that deadline, the lender must file for foreclosure and present a summons to appear before the magistrate. As the ship hops from star to star, the lender may find that previous hurdles need to be repeated: some clerk - perhaps incompetent, perhaps failing to get the expected "fee" from the lender, perhaps bribed by the player or by some meddling third party - failed to enter the notice in the computer correctly, rendering it invalid; or some judge has a private disagreement with the lender's agent and arbitrarily finds some "problem" with the lender's paper trail. As far as I know, there are only hints and clues about the process: you as gamemaster can use those to buy your players time - or you can just drop the axe and leave the players grounded at the first bad roll.
As near as I can tell, CT Book 2 doesn't say anything more than that
something happens, and MegaTrav (Imperial Encyclopedia) just parrots CT Book 2. It's up to you what that something is.
