Project guide asks for authorship without any contributions – how to proceed? Our computer-science curriculum mandates that we produce a paper about a research project:


We set the topic.
We get a professor assigned as a project guide.
The paper has to be published at a peer-reviewed venue.
The paper is also reviewed and marked by some professors.


For us the project guide was assigned at random and not according to our wishes. Her domain is completely different from what our paper is about.

Our project guide never reviewed our project, helped write the paper, or contributed anything else to the project.
She did not show any interest in our project and kept putting us down.
She was only interested in the publication scope of the project.
We sent our paper to the project guide multiple times for review and she didn’t notice her name was not among the authors then.
The paper has already been published in a peer-reviewed journal.

Now, our project guide asked me why her name wasn’t included, and the college is saying they wouldn’t award marks because of her name not being included.
I don't believe my college has specific rules for authorship.

What would my next action be?
Let’s start with what is going wrong here:


Requiring you to publish something peer-reviewed on the level of coursework is at least dubious. For more details, see Is it ethical for departments to have publication requirements for students
Putting somebody as an author of a paper who made no contribution at all goes against all standards of academic authorship. However, violating this is so common in some countries and fields that many professors may not even be aware of it.
The project guide is abusing her power when she pushes you into giving somebody authorship (who doesn’t deserve it).
If your institution via rules or coercion makes you give somebody authorship (who doesn’t deserve it), this is also an abuse of power.


Now, you have to evaluate the situation to pick your enemies and allies, if any:


If the curriculum has any written rules that you should make somebody a co-author, you can fight those rules – if any professors or a higher power cares about this. In my country, I don’t see much of a problem of turning this into a public scandal, but yours is probably different.
If there are no written rules about authorship, and one of the other professors evaluating your project or a dean of students or similar are trustworthy, you can present the situation to them and try getting them onto your side. At the very least, you may score some points if you can provide evidence that your project guide did not tell you about any authorship aspirations or rules earlier and also did not do her job properly.
The journal (if reputable) will not be very happy if not completely refusing to change authorship retroactively. You could find an ally here (just tell them what happened), but whether the journal has sufficient power over your department is hard to say.
It could sadly be that your institution is full of power-abusing professors and in a position that allows them do this. In this case, the only thing you can do about it is to leave.
