End of Season 6. Lifeline.
There's an admiral who thinks the Maquis are criminals under house arrest who should be tagged and monitored, who is going to throw them in jail in just 5 years, when the relief ships rendezvous with Voyager.
Didn't see that here: http://www.chakoteya.net/Voyager/622.htm
Individual trials would have put Lon Suder and B'Elanna into confinement away from the ship's guts and particulars.
Believe me, I'd've liked to see B'Elanna get a court martial, for assault if nothing else! Having her have pervasive behavior/anger issues would have given her far superior character development potential.
An individual Trial might have even unmasked Seska, who should have been a friend, since the Federation and the Union were allies at the time.
Seska could have wound up as an ally regardless. And a useful one at that.
