Pakistan's impending 21st amendment

In the United States, the 21st Amendment to the Constitution repealed Prohibition (the 18th Amendment). In Pakistan, the 21st Amendment, which is now in the works, will have a very difference valence. AAJ News is reporting early information on the legislative path under consideration for amending the Constitution to permit the establishment of military courts to try civilians. Step 1 would be enactment of a “Constitutional (twenty-first) Amendment Bill, 2015.″ Presumably that would be followed by implementing legislation. A military officer would be substitute for a judge of the High Court. The arrangement is to last for two years (unless of course the amendment is itself amended in the future).
