In June 2022, Mass was appointed as junior counsel to the UK Covid-19 Inquiry by Baroness Hallett, Chair of the Inquiry.

Mass was instructed in this inquest to represent the family of a man who was died after a venous needle dislodged from his dialysis machine and caused him to lose a significant amount of blood. The dialysis machine alarm parameters were incorrectly set and so these failed to alert nursing staff to the dislodged venous needle. In this regard, the Coroner’s conclusion noted “The parameters to trigger the alarm had been set much lower than usual practise or policy on the unit”.
Mass was instructed in this two-week jury inquest to represent the family of a man who was sectioned under s.2 of the Mental Health Act 1983 but nonetheless managed to abscond from hospital before jumping from a bridge and ending his life. The deceased had previously been assessed to have represented a suicide risk and a risk of absconding. Furthermore, he had previously successfully absconded on two separate occasions in the days leading up to his unfortunate death. The Jury returned a narrative conclusion which stated “[…] failures in information recording and sharing, and failures to provide appropriate staff to mitigate an accepted risk of absconding and self-harm contributed to his death.”
Mass was instructed in this multi-day jury jury Inquest which investigated the death of a 14-year-old boy who died following a road traffic accident. The road traffic accident occurred shortly after the police commenced a pursuit of the vehicle that the deceased was travelling in. The Inquest explored questions around (a) the appropriateness of the police pursuit; (b) the adequacy of police communications in the build-up to the pursuit; and (c) the appropriateness of medical intervention following the collision. The inquest was the subject of significant press attention and was covered in national and regional press outlets.
Mass was instructed in this multi-day inquest to represent the family of a man who died in a nursing home after he mistakenly pulled out his tracheostomy tube and staff were unable to re-insert it. The Coroner returned a narrative conclusion which noted that the deceased was discharged from hospital to a nursing home without the requirement for “one-to-one care [being] included in updated communications between agencies” and without “funding for it [being] in place”.
Mass was instructed in this inquest to represent the family of a lady with depressive order and psychotic symptoms who committed suicide during a period of overnight leave from hospital. The Coroner concluded that relevant risk assessments were compromised because there was a failure to consider that the deceased was “at an elevated risk of suicide” and her family were not informed of there being any risk of suicide.
Mass was instructed in an inquest to represent the family of a man who died in hospital after being diagnosed as having sepsis and appendicitis. The coroner returned a narrative conclusion which included a comment that the deceased died “in part due to the late diagnosis”.
Mass was instructed in this multi-day jury inquest to represent the family of a man who died after falling from the window of a nursing home. The jury returned a lengthy narrative conclusion which recognised that the deceased’s death was avoidable. The narrative included (amongst other things) the statement that “there was a failure to meet health and safety guidelines which the home had a responsibility to be aware of.” Furthermore, the coroner issued a regulation 28 prevention of future deaths report. The inquest was covered by various press outlets.

Mass was asked to advise multiple football fans who visited the stadium of a Premier League Club but were injured after opposition fans infiltrated the area designated for home fans and started a fight.
Mass was instructed to represent a football player charged with Assault against a match official. The matter was heard by the FA Serious Case Panel at first instance who found the player guilty of assault and (amongst other things) banned the player from all footballing activities for a period of 5 years. Mass represented the player on an appeal to the FA Appeal Board which overturned the decision. Mass successfully argued that the player was instead guilty of a lesser offence of ‘Improper conduct against a match official’ (to which he pleaded guilty). As a result, the player’s footballing ban was reduced from five years to just one year.
Mass represented a football club charged with playing an ineligible player in four different matches. Mass successfully argued that any charges relating to the first two games were time-barred and that mitigating circumstances relating to the third and fourth matches meant that any punishment should be minimal.
Mass was instructed to represent a football player charged with (1) improper conduct aggravated by reference to a person’s colour and race; (2) improper conduct including foul and abusive language; (3) improper conduct including threatening behaviour. Following Mass’s early intervention in the matter the case was closed against his client without the need for a hearing.
