"On May 9 the National Legislative Assembly (NLA) enacted the Cyber Crime Bill, which will come into force within 30 days after His Majesty the King endorses it."

The bill came in effect on July 18 (or whereabouts), so either the King took more than 30 days to sign it or there was a period of time before it was forwarded to his office. This article is dated June 18 - exactly a month before announcement in the Royal gazette. Or it's just sloppy reporting.

Things like this are impossible to get exactly right and I never claim total accuracy.
