Standing your ground while maintaining a logical and rational approach is the only way to deal with them.
Most of them like a fight, so you simply can't pick one with them.
I remember one time where I was discussing a problem with a manager in another team. Every single email he sent, he CC'd the management 2 levels up. Every single email I sent, I sent directly to him only. My colleague was panicking. He felt that I needed to show my side of the story to upper management or else I would be in trouble.
Eventually the management 2 levels up got frustrated: "Why am I getting all of these emails? Why can't you people sort out this problem yourself?" To which I reasonably replied, "I'm very sorry that you've been bothered, and I'm not sure why this person is being so difficult. Now that you are here, would you mind giving us a hand?" Problem solved.
Thanks for pointing this out.
They are likely to repeat the attempt if they think they can get away with it on you.
Easy to test.
1. Send back the document he sent with a copy of your most recent edits and ask him to confirm if his document is correct.
2. But, make note of at ONE error, and see if he fixes all of them.
3. If he only fixes only the one, then he's either really lazy or trying to keep up the deceit.
4. Repeat steps 1 to 3, be sure to CC everyone involved. If he's lazy he will be ashamed and be more careful. If he's a sneaky bastard he will most likely get angry.
Not foolproof, but will sure make everyone aware of what is going on. (regardless of the motives)
