The NLA passed the bill without amendments although some members wanted to add a clause to prevent ex-TRT members registering a new party under the defunct name. Otherwise, they believe, the Constitution Tribunal's ruling would mean nothing in practice.
NLA member Praphan Khoonmee said the clause would be added in a new draft law on political party instead.
The bill aims to amend Announcement 15 issued by the Council for Democratic Reform (CDR), which prohibits political party-related activities and registering of new parties after the coup of September 19.
The NLA last month rejected a Cabinet proposal to consider the bill in three consecutive readings. The delay means the period of the ban would still be valid until the NLA approves a revised version, which is not expected for at least a month.
