This summary is not the rule. The rule text controls.
If a lawyer is found to be personally incapable of practicing law, the court will take away their license to practice until further notice. This isn't a punishment for breaking rules. It's a step taken when something about the lawyer's personal condition, like a serious illness or mental health issue, makes it unsafe for them to keep representing clients.
Once suspended under this rule, the lawyer cannot go back to practicing law on their own. They have to ask the court for reinstatement, and only the court can decide to lift the suspension and let them practice again. This means the lawyer needs to show the court that whatever caused the problem has been resolved or is no longer a concern.
For clients and others involved in cases, this rule matters because it protects people from being represented by a lawyer who isn't able to handle their legal work properly. It puts the responsibility on the court to make sure lawyers are fit to practice before allowing them back into the profession.
