3 more years proposed for Pakistan's 21st Amendment

This editorial in the Pakistan Observer recommends that the country's 21st Amendment, permitting the trial of civilians by military courts, be extended for three years. Excerpt:

There was no justification to keep the two-year condition when the lawmakers and policy-makers knew well that there was no imminent end to the menace of terrorism. However, two-year timeframe was supposed to be utilized by the federal and provincial governments to strengthen normal judicial system and come out with foolproof mechanism to dispose of cases of terrorism expeditiously, which unfortunately has not been done. Therefore, there is every justification to extend tenure of military courts at least for three more years so that they are able to clear all the cases referred to them.

What are the odds the amendment will be extended?
