Emergency out, but not 6,000 detainees
The fate of around 6,000 people who are being held in detention under emergency regulations which lapses on Tuesday will be decided by the Attorney General, a senior Justice Ministry official said.
Justice Ministry Secretary Suhada Gamlath said that though the state of emergency would lapse on Tuesday, there would be no automatic release of the detainees as there were other laws under which they could be held.
When the House meets on September 7, the Government will move an adjournment motion, thanking the President for lifting the Emergency amidst speculation that amendments to the Prevention of Terrorism Act or new laws will also be introduced to maintain some of the security restrictions.
