The proposed amendment to the Sri Lankan Constitution is in the works. I have not even read it completely and I would not have time for a while either. I am busy doing what I am supposed to do, studying.
The End, (Also known as the start) has the best write up on the matter that I found so far so if you are interested, follow the link below and read it. If I find any other documents, I will surely will post them.
Be good to Magerata.
