Im not sure on this one. Couple of things that you should clarify. Is the new trade equal to the old trade in your eyes in terms of equal value for players involved? If so then the only person who should have a real problem is the guy who originally had the trade pending which was cancelled because he misses out on potentially making his team better. I think if a trade is agreed upon and going through the voting period it should be ok for an owner to back out by emailing the commish and saying they changed their mind. Now if this new trade is much better for one team than the other then it I would say its shady as hell and give the commish a royal beat down.
Worse than this is when your in a money league (as I am) and you have jackass owners who make trades simply for the sake of being active. We had one guy, Ill call him Mr. X, made 5 I repeat FIVE trades in the first three weeks which first made his team great then made it terrible and he shipped a bunch of talent into my division and stacking this other guys team so he's basically unbeatable:
1st Trade - Mr. X gets - Horn, tiki barber, Shockey, he gave up Ricky Williams, STacey Mack and Drew Bledsoe
2nd Trade - Mr X gets - Preist Holmes and Alge Crumpler, he gave up Fred Taylor, Torry Holt, Shockey (this was the one that really pissed me off because the guy who used to have priest is terrible at fantasy football)
3rd Trade - Mr. X gets Shawn Alexander, Curtis Conway, he gives up Tiki Barber, Garrison Hearst, Joe Horn.
4th Trade - Mr X got Galloway, C.Rodgers, and Derrick Mason, he gave up Harrison and Pinkston.
5th Trade (the one you cant possibly understand) - Mr X got P.Price, B.Farve, and Duece McALister, and he gave up PRIEST HOLMES, Alge Crumpler, and Moe Williams. NOt only that but he made this trade with our Commissioner who he also works in the same office with.
Needless to say I hate Mr. X more than anything, our commissioner now has a team that is averaging 120 points/week and is so much better than anyone else it will take an injury or two for him to come back to earth.
So next time you guys wish for shithead idoits like Mr. X to join your league because they make bad trades and are easy money, remember it can bite you on the ass if your the type that likes to keep his original players and not the guy wheeling with him like me......
