Not the only way. It would (in theory) be possible to bring in legislation that sets a different test from Gillick competence that should be applied in GD cases where the patient is below the age of 16.
Yes, true, but the point in the original case seemed to be that the judge was pointing out that GIDS was failing to apply Gillick competence, and the ruling was an attempt to correct that.
If the point of law is that the judges can only rule on Gillick competence in individual cases, and that what the former judge did was effectively an unofficial attempt to create a different test from Gillick competence, then it’s likely to be concluded he overstepped the mark in much the same way the judge in Maya’s case did.
One of the problems with all these cases is that they are so mired in emotion (on both sides) that even judges get sidetracked. If the original judge in Keira’s case was utterly shocked at what was being done to children, he might well have overstepped the legal rules constraining him.
It strikes me sometimes that our judicial systems all too often become hung up on points of law which prevent them from actually adjudicating between right and wrong.
