The university, at which Berlin's top SPD candidate Franziska Giffey completed her master’s degree, is not examining new allegations of plagiarism against the politician.
In the case of a master's thesis, a period of five years applies, which has now expired, said a spokeswoman for the Berlin School of Economics and Law (HWR) on Friday upon request.
Giffey completed her master's degree in 2005 at the University of Applied Sciences for Administration and Justice Berlin (FHVR), a predecessor of the HWR Berlin.
New allegations of plagiarism had become known against the former Federal Minister for Family Affairs.
Anatol Stefanowitsch, professor of linguistics at the Free University of Berlin (FU), has been studying these for some time.
Giffey did not quote correctly 62 times on 26 pages and thus violated scientific standards, he criticized in an interim report that was available to the German Press Agency on Friday.
The online portal t-online reported about it first.
The Free University revoked Giffey's doctorate after reviewing her dissertation in June.
The university announced at the time that the doctoral degree was obtained through “deception about the independence of its academic performance”.
