Constitutional principles
Charter
The charter turns the doctrine into rules that power has to obey.
What the charter is for
The charter is not written to sound impressive. Its job is to make certain political temptations harder: permanent emergency, unreviewable expertise, public manipulation, ecological deferral, and responsibility without a named decision-maker.
What it protects
It protects correction, due process, public reasons, ecological limits, and future optionality. It also prevents the doctrine from becoming a loyalty test or moral religion.
How to read it
Read it as a constraint document. It is less interested in slogans than in what a state is not allowed to do when stressed.
