The couple was found in their apartment by family members on Feb. 19, 2018, after they had taken the drugs. The couple was rushed to the hospital and given an antidote to the medication. Mavis survived; Dennis did not.
After the hearing, Joy Munns, a daughter of Dennis and Mavis, called for the legalization of assisted suicide "so that dying people aren't forced to suffer, make plans in secret or ask loved ones to risk prosecution by helping them," the BBC reported.
Both euthanasia and physician-assisted suicide are illegal under U.K. law. According to the U.K.'s National Health Service, euthanasia could be prosecuted as murder or manslaughter and carries a maximum sentence of life imprisonment, while physician-assisted suicide carries with it a maximum punishment of 14 years imprisonment.
In 2015 the U.K. parliament rejected a bill that would have legalized assisted suicide for patients with a terminal diagnosis, by a vote of 330 to 118.
The U.K.'s Suicide Act 1961 was challenged in High Court in 2017 by a terminally ill man, Noel Conway, who wanted a doctor to be able to prescribe him a lethal dose. His case was dismissed.
Some disability groups in the U.K. and throughout the world have argued against legalized physician-assisted suicide and euthanasia, saying that such legislation would put vulnerable populations such as the elderly, physically disabled and mentally ill at risk for coercion.
