Qisas shall not be executed until all the wali are present at the time of execution, either personally or through their representatives authorised by them in writing in this behalf:

Provided that where a wali or his representative fails to present himself on the date, time and place of execution of qisas after having been informed of the date, time and place as certified by the Court, an officer authorised by the Court shall give permission for the execution of qisas and the Government shall cause execution of qisas in the absence of such wali.
