Key legal question
Whether the salary of the ETI professor had to be fixed as for a full-time post.
Extracted holding
No; the applicable rules treated ETI lecturers and titular professors according to the teaching load, and the promotion to titular professor did not change the salary class.
Extracted reasoning
The court held that the legislature intentionally made titular professor an essentially honorary promotion without automatic salary increase; 10 weekly teaching hours justified only 10/12 of the annual salary.
