This question concerns the Justice League and the Justice League Unlimited television series within the DC Animated Universe.
In Justice League episodes 50-52 (Starcrossed), it is revealed that Hawkgirl was working undercover for the Thanagarian military. Her information about Earth and the Justice League's weaknesses allowed the "Hawkmen" to capture the Justice League and, unbeknownst to her, build a hyperspace bypass generator that would destroy Earth.
At the end of the episodes, the Justice League (with Hawkgirl's help) destroy the hyperspace bypass generator and save the Earth. Because of her treachery, the other members of the Justice League hold a meeting to vote on Hawkgirl's continued membership within the Justice League. The result of the vote is never disclosed due to Hawkgirl's voluntarily resignation from the league. However, it is obvious that the Flash voted for her to stay; it is also obvious through this episode (and several others in Justice League Unlimited) that Wonder Woman wanted to expel her from the League.
In Justice League Unlimited episode 11 (Wake the Dead), it was revealed that the original League voted for her to remain in the Justice League. It was also revealed that Green Lantern abstained from voting and Superman "broke the tie." This means that only 5 individuals voted with the end result being 3-2. Superman's, the Flash's, and Wonder Woman's votes give a preliminary result of 2-1. That leaves Batman and Martian Manhunter to fill the two remaining (opposing) votes.
Is there any indication (in other episodes or otherwise) on how these two voted?
