I understand the principle, and agree with it in general. In this particular case, though, the legal system understands he did delegate his strategy by delaying his change of lawyer in a way that could be interpreted as exploiting a loophole to keep his trial being delayed in order to avoid the death penalty. So, in one extreme, you have the right of the individual to choose how the counsel should act, and in another extreme, if you let an individual abuse that right, you create a loophole by which a guilty criminal can postpone their trial basically indefinitely. Basically, if this was software engineering, they found a strange behavior of the system, and are trying to define if this is a bug or a feature. That’s why the case is in the Supreme Court - it’s them who will decide if this is legal or not.
