250,000 Students Sign Petition to Invalidate Grace Mugabe's PhDThe Zimbabwe National Students’ Union (ZINASU) claims that over 250,000 college and university students in the country have signed a petition to be used in court to challenge the validity of First Lady Grace Mugabe’s philosophy doctorate. ZINASU president Gilbert Mutubuki says his organization is collecting more signatures, which will be submitted to court with other documents to fortify their case against the University of Zimbabwe’s Chancellor President Robert Mugabe, Vice Chancellor Levy Nyagura, and the higher institution of learning. Mutubuki says they are taking this matter to court to protect the integrity of the university as the recent awarding of the doctorate to the first lady has been questioned by students, lecturers, university stakeholders and other people worldwide. Mrs. Mugabe’s aide, Lawrence Kamwi, refused to discuss this issue saying he does not talk to Studio 7. UZ Dean of Students Dr. Munyaradzi Madambi was not available for comment as his mobile phone was not being answered. Independent human rights lawyer Job Sibanda says what matters in this case are facts on the awarding of the doctorate and not thousands of student signatures. The students argue that they have failed to obtain the necessary information relating to the first lady’s enrolment at the UZ, a situation they say has raised suspicion over the way her doctorate was awarded.
