In 2019, Morris was brought into controversy over past abuse cases whilst working at Trinity Hall, an educational institution where young students reside on site. A lecturer sexually harassed 10 students and was allowed to return and continue attending certain events, with Morris (as master) issuing the following statement: "In line with the rights and privileges afforded to Emeritus Fellows of the College, Dr Hutchinson will continue to attend certain College events and to exercise his dining rights, but will not attend events primarily aimed at students or alumni except by agreement with the College." This was two years after Morris was quoted in
The Guardian and
Varsity as recognising the "seriousness and the formal nature" of the complaint. Human rights barrister
Charlotte Proudman said, "The college has given fellows a licence to abuse their power with impunity. Women students are not safe in their own colleges"; while
The Guardian called it "a gross betrayal to the students", and "a dangerous environment for women students to study". Two weeks later,
The Daily Telegraph reported Morris' announcement that a sexual harasser had resigned from his post. Morris said that he would launch a review into the college's handling of the case. Following the preliminary hearing of the
Independent Inquiry into Child Sexual Abuse within the Church of England, Morris talked about his own sexual harassment: Back in the 80s, I was slapped on the bottom on several different occasions by a clergyman at the church I attended. I was taken aback, a bit shocked even, but I was unsure what to think. It was in the presence of his partner. Was it simply playful? Was it a kind of advance? It was certainly unwelcome. But I didn't say anything at the time, and now realize I probably should have done. I think I rather minimised the matter, assuming most people would go for the 'he's just being light-hearted' line and it wasn't worth making a fuss. Also, I rather liked him, and didn't want to make things difficult. A common enough reaction, as I realise. But looking back, it's significant I remember distinctly each occasion, and the very fact that I didn't want it to happen and that it was a repeated pattern puts it in a different light today. In February 2020, Morris stepped aside as Master of Trinity Hall "while an investigation into procedures" was conducted. The college commissioned an independent inquiry led by Gemma White QC which recommended Trinity Hall consider disciplinary action against Morris in relation to his handling of one allegation. Morris resigned as Master in August 2021. Trinity Hall published the report of Gemma White’s inquiry on 8 September 2022. In response Morris published a statement on his website which included the statement: "I realize that my handling of the allegation made by 'John' was not as thorough as it ought to have been, and for the distress he has suffered as a result of my decisions I am very sorry. I never prejudged this matter, believed I was following the legal advice I had been given, had strong support for my actions from all my senior colleagues bar one…I have learnt from my failure to question the legal advice I received, and I continue to be committed to the safeguarding and well-being of all students. I have always strongly supported Cambridge University's 'Breaking the Silence' initiative. I am also grateful for Gemma White's acknowledgement of the positive contributions she received from people I have supported over the years, including those who presented as survivors of sexual violence." ==Honours==
