Judge blocked her attempt to keep her name secret during the hearing

A highly controversial senior coroner is facing serious allegations that she or her staff removed parts of a transcript and recording of her hearing into the death of a talented and hardworking ITV news editor Teresa McMahon who was found hanged at her home four years ago.

Mary Hassell found that she committed suicide and ruled out that she was subject to ” coercive control” by her ex boyfriend, Robert Chalmers, an NHS estates employee, who had previous convictions for violence. Mary Hassell believed the words of the pathologist ,Dr Mohammed Bashir, who examined the body but kept no photographic evidence and discounted domestic violence and Greater Manchester Police who decided from the start that no crime had been committed and never took any photographs either at the scene of her death.

Throughout the hearing this version was challenged by Teresa’s aunt, Lorna McMahon, who was frequently interrupted by Mary Hassell when she raised questions about the competence of Greater Manchester Police in handling the investigation into her niece’s death.

I was present at the hearing at the hearing with many other journalists. My report on it is here.

Yesterday’s hearing at the Royal Courts of Justice was meant to decide whether the court could give her permission to bring a judicial review into Mary Hassell’s hearing claiming her conduct was irrational and procedurally unfair in coming to her verdict.

But the hearing took a completely different turn under Mr Justice Stephen Morris when Lorna McMahon, having obtained both the transcript and audio recording of the hearing said parts of both, covering descriptions of previous violence against her niece by her ex boyfriend had been omitted.

It also emerged from correspondence I have seen from Mary Hassell’s lawyers and a public ruling by a previous judge Mr Justice Kerr, that the coroner had tried to get her name kept out of the public domain during the hearing.

Her lawyers claimed ” it was customary” to be not named. She wanted it done under ” the slip rule” which meant there would be no hearing about the application. The judge ruled this procedure could not used in this way and rejected her application because it raised issues of ” open justice”.

When Mr Justice Morris heard Lorna McMahon’s evidence he weighed up whether to continue the hearing or adjourn it to allow her complaint to be properly looked at and for her to provide evidence from other people at the original hearing – including members of the public and journalists – to back up her claim.

All sides in the case agreed it was an extremely serious allegation which could be viewed as a criminal case of perverting the cause of justice.

Her own lawyer, Jonathan Glasson KC, agreed as such and but added by adjourning the case until the late autumn it meant that the accusations against the coroner were left hanging over her for some weeks.

The judge also made it clear by adjourning the hearing it did not mean that he was convinced about Lorna’s case and said she would need more evidence.

The directions he gave are worth reporting in full:

IT IS ORDERED THAT

1. The application for permission to apply for judicial review is adjourned

2. By 4pm on 12 August 2025, the Claimant is to file and serve a witness statement, verified by statement of truth, identifying any and all parts of what was said at the hearing of the inquest by the Defendant on 5 December 2024 (“the Hearing”) which she contends have been omitted from the audio recording of the Hearing provided to the Court and the Claimant by email dated 14 July 2025 at 513pm and sent by Payne Hicks Beach LLP (“the Audio Recording”).

At the same time as filing and serving her witness statement pursuant to paragraph 2 above, the Claimant is to file and serve any and all witness statement evidence from others (including witnesses called at the Hearing and/or members of the press and/or members of the public) in support of her contention that parts of what was said at the Hearing have been omitted from the Audio Recording.

6.As soon as possible thereafter, the matter is to be placed before a judge (if possible, Mr Justice Morris) on the papers to consider directions for the progress of the case, and in particular whether there should be a further oral hearing dealing with the matters covered by paragraphs 2 to 4 above, taking account of all necessary reasonable adjustments.

7 The case to be reserved to Mr Justice Morris, if possible.

8. Costs of the adjournment and of the matters raised above reserved

This is the second recent case where there has been controversy about Mary Hassell’s handling of inquests.

Earlier that year she held an inquest into the tragic death of Gaia Young,25, who  was rushed to accident and emergency at University College Hospital with severe headaches only to die of an unexplained brain condition and doctors have yet to correctly diagnose what was wrong with her.

Again Mary Hassell  patronised and showed no empathy for her bereaved mother, Lady Dorit Young, who had lost her only child ,Gaia, and failed to properly investigate her death. The full story is on the Truth for Gaia website. She even blocked her from making a statement at the inquest. I reported that hearing and you can read about it here.

The treatment of both relatives led to a protest outside the coroner’s court during Teresa’s inquest. Pictures are below.
