What should you do if coauthor refuses to work on paper and refuses to consent to submit it? My old PhD adviser and I had a falling out. We wrote a paper together, it is done at this point in my eyes. He "disagrees". Near the end of revisions the edits became more and more banal and even flip flopping. "Do it this way, no change it back, no change it back, no change it back etc" endlessly. I have shown the paper to other faculty and they think it looks fine. 

We got into an argument about this, the paper has been done for well over a year at this point. I have a new adviser. At this point the old adviser flat out refuses to submit the paper, he refuses to make any edits to the paper, he refuses to even talk to me. 

The grad head has been notified, other professors have been notified. My current adviser is really pissed off about the whole situation and is planning on talking to the old one. 

Can he just not submit the paper? Do I have any recourse? I wrote the paper, I did the majority of the work (other than his idea etc). Can I just submit it myself? I feel like he would email the journal and complain about it. But I don't see any other choice.
No, you probably can't just submit it yourself if the prof is validly a co-author. You need his permission, just as he needs yours. 

But I suggest that you let the two professors fight it out among themselves. That could result in a good result for you, and probably not a worse one. Professors sometimes don't mind behaving badly in front of students, but are less likely to with colleagues. Collegiality is still valued in most places. If it needs to get escalated, let the new advisor do it also, on your behalf.
