R (Nicklinson and Lamb) v Ministry of Justice  EWCA Civ 96.
In short, the decision was that (1) a defence of necessity cannot be fashioned at common law as a means of protecting a person who assists in the suicide of another; (2) the legal prohibition against assisting was not a disproportionate interference with Article 8 rights but (3) the Director of Public Prosecution's policy relating to prosecutions under section 2 required some amendment to provide greater clarity as to when certain individuals might be prosecuted. That would enable individuals to have greater foreseeability of the consequences of assisting. Point 3 will be of particular importance to the medical profession. Lord Judge dissented on point 3 - ' ...we cannot keep ordering and re-ordering the DPP to issue fresh guidelines to cover each new situation... [para 179]
At the time of writing, it seems very likely that this case will proceed to the Supreme Court. At the heart of the judgment lies the fact that the Suicide Act 1961 is a clear prohibition against assistance in suicide decided by Parliament and set in legislation though prosecutions may only be brought with the consent of the DPP who applies the guidance arrived at following the House of Lords decision in Purdy. Parliament has, so far, not acted to amend the law and as recently as 2009 can be taken to have affirmed it when section 2 was amended by the Coroners and Justice Act. There are very difficult moral judgments at play and it was for Parliament to act as what Lord Judge referred to as 'the conscience of the nation.' At para 155 he said:
The circumstances in which life may be deliberately
ended before it has completed its natural course, and if so in what
circumstances, and by whom, raises profoundly sensitive questions about
the nature of our society, and its values and standards, on which
passionate but contradictory opinions are held. Addressing these life
and death issues in relation to life before birth, the circumstances in
which a pregnancy may be terminated were decided by Parliament. The
abolition of the death penalty following the conviction for murder was,
similarly, decided by Parliament. For these purposes Parliament
represents the conscience of the nation. Judges, however eminent, do
not: our responsibility is to discover the relevant legal principles,
and apply the law as we find it. We cannot suspend or dispense with
primary legislation. In our constitutional arrangements such powers do
not exist. They are not vested in any one or any body. Parliament
itself cannot suspend or dispense with primary legislation. It may
enact new provisions amending the law. When it does so, the change
follows as a result of fresh legislative enactment which, far from
suspending or dispensing with the law, confirms that a suspending or
dispensing power is a stranger to our constitution.
and at  Lord Judge added:
The issues with which these appeals are concerned
have been addressed in Parliament on a regular basis over many years
without producing the result sought by those who advocate change. The
legislation which criminalises assisting suicide is recent and
unequivocal. Even if (which it is not) it were constitutionally
permissible for judges to intervene on the basis that Parliament had
failed to address a desperately urgent social need, it cannot be said
that Parliament has ignored these issues. Therefore whatever the
personal views of any individual judge on these delicate and sensitive
subjects, and I suspect that the personal views of individual judges
would be as contradictory as those held by any other group of people,
the constitutional imperative is that, however subtle and impressive the
arguments to the contrary may be, we cannot effect the changes or
disapply the present statutory provisions, not because we are abdicating
our responsibility, but precisely because we are fulfilling our proper
