This question is somewhat inspired by the question in When is a supervisor unable to request paper retraction if a paper gets published without her consent?, although I've no reason to suppose that the following situation describes the one prompting that question.
Suppose Alice and Bob do some research together, with Alice providing ~75% of the intellectual contribution (perhaps Alice is Bob's PhD student). Alice writes a draft of the paper, and lists both of them as authors.
Bob does not agree with part of what Alice has written, and says he does not agree to the paper being published in this form. Alice, however, is not willing to remove the offending section. (For the sake of argument, let's assume that neither Alice nor Bob can be said to be objectively 'in the right'.)
Is there any route out of this impasse? Can Alice treat Bob as refusing authorship of the paper, and publish the manuscript without his name?
