yes, I know, wb. Was just mentioning some of the stuff that surrounds the case, rather than the strict legal turning point.
I can see the DPP might have thought it was preferable to leave it as a grey area, with each decision made on the facts of the relevant case. A clear policy risks being too harsh, either 'we will uphold the law and prosecute anyone who accompanies people to Switzerland' or the abolition of assisting suicide as a crime - which would risk people being coerced.
But in fact all that does is leave people like Debbie Purdy twisting in the wind, facing the horrible prospect of having to journey and die among strangers, or equally horrible prospect of risking her husband's freedom.
