My coauthor and I work at some organization. After I started working with him, people told me that he allegedly took some data (used in the paper) from the organization without authorization (He was let go from the organization.)
I received a letter from the organization stating that he indeed took the data without authorization. He explained that if I finished the paper he will send the paper to the organization for clearance. I asked him to show me the document, but he only replied: “I am in good relation with that organization.” So, I gave him benefits of doubts and I did all the work, including every calculation.
While he had been claiming that “the data breach is a rumor”, I confronted him over the phone and he finally admitted that the data breach is a fact. I myself have acquired clearance with the organization regarding the data breach since then. However, he refuses to withdraw from the paper.
As for the paper, I have proved every single result, every single calculation, and every single sentence of the paper. He did not do anything. I asked him and he cannot define a very basic term used in the paper. He said: “But it is not honest to ask me to remove my name only by simple assumption like the one you raised.”
I would think of proceeding as
- ask the coauthor to provide me the formal paperwork on this issue,
- if the coauthor fails to provide me these documents then I would need to drop him from the paper.
Do you think it make sense? Are there any other procedures that I need to follow?
