bad faith

1. Deceptive or dishonest behavior. I'm afraid there will be many more instances of bad faith as this campaign continues. I don't think it was just a simple mistake, though—I think it was bad faith on her part. Of course I don't want to see him—he was working with my enemies the whole time! That kind of bad faith is hard to overlook.

2. Distrustfulness. There's too much bad faith between us. I mean, how can I trust her now, knowing that she stole all of that money from our company? It's really impossible to negotiate in bad faith like this. Do you think the prosecution will be able to prove that the defendant showed bad faith when he drew up that contract?
