The principal of Abertay University, who was suspended from his post last week, is taking his case to an employment tribunal.
Prof Bernard King has lodged tribunal papers maintaining he was discriminated against because of his age.
The principal, 64, claims the university's governing body reneged on an agreement to extend his contract.
Abertay said it would not comment until it had completed an inquiry into issues raised with university court.
It is believed the papers lodged with the tribunal include claims and counter-claims of intimidation and breach of agreement.
Last week, a former member of Abertay University's governing body criticised the suspension of Prof King.
Derek Douglas, a leading figure in Scottish business, called for an independent inquiry into the case.
He said he was concerned that, if the suspension was unwarranted, the university's reputation may be damaged.
Prof King was relieved of his duties last week, while an investigation was launched into a number of unspecified issues raised with the university court.
The vice-principal, Nicholas Terry, was also suspended last month, following what the university said was a separate issue.
