What are legal consequences of plagiarism?

Plagiarism should not be confused with copyright, which is quite a different thing. For a student more immediate (and more probable) consequences of plagiarism include:

1. Much reduced grade.
2. Starting or continuing a reputation for plagiarism.
3. Assignment not counting.
4. Seminar not counting.
5. Having to repeat a semester or year.
6. In extreme cases, expulsion.
