The Problem: You view yourself as the legal ruler of Gaza, but Palestinian law only empowers that rival president in Ramallah to sign off on executing collaborators.
The Solution: Change the law, as described by ABC News:
But Palestinian law dictates the president, now Mahmoud Abbas, must sign off before a sentence is carried out – something he has been reluctant to do.
But Mahmoud Abu Rahma says Hamas rulers in Gaza who refuse to recognise the president's authority are now illegally approving the executions themselves.
"Now the basic law states that the prime minister assists the president in implementing the law," he said.
"They interpreted this as the prime minister, for them in Gaza, Mr Ismail Haniyeh, can actually assist the president in implementing the court rulings, which includes the death penalty."
The Outcome: You now have a veneer of legal cover for your latest witch hunt.
