RE:Re:No renewal for Didipio - the backgroundAn interesting read on the FTAA agreement.
Particularly Section XVI and XVII.
Also interesting that OGC can remove all of its equipment if the agreement is terminated or expired
Lot of complications can be put in the way by an adverserial party ( not necessarily the government ), which might take a while to work out. It does not look so cut and dry ( legally) that OPG can be just kicked out. This may explain, somewhat. the long drawn out process.
