N is the first author for a paper (PhD work) and there are three co-authors, B, C and D.
B and C are from the same department and the author D is from different department but they are all from the same institution. B had the biggest contribution in terms of the experimental work and N spent a long time writing the paper.
The paper was sent to all for revision. After the paper is ready, the co-author submits the manuscript considering herself as the corresponding author without the first author permission. The problem is that she gave an incorrect email address of the first author to the journal.
Is this situation illegal? Can the first author contact the journal and at least change his correct email address?
