The Bhumjaithai Party has tabled a bill seeking to revoke some orders and announcements issued by the now-defunct coup-makers, the National Council for Peace and Order (NCPO), that remain in force.
The party says these orders and announcements violate people's rights.
Saritpong Kiewkong, a Bhumjaithai MP for Krabi, submitted the bill on Monday to Areepen Utarasint, an adviser to the parliament president, who accepted it on behalf of the parliament president.
Mr Saritpong said Bhumjaithai leader Anutin Charnvirakul had assigned the party's legal team to study complaints from several organisations about some orders and announcements issued by the NCPO which remain in force and are seen to violate human rights principles.
He said that the NCPO issued 240 orders and announcements, of which 71 were turned into laws.
The NCPO, led by former prime minister Prayut Chan-o-cha, staged a coup to oust the Pheu Thai-led government in 2014.
Mr Saritpong said the party's legal team has also found that another 37 orders and announcements can be turned into laws.
He added that the orders and announcements issued by coup-makers are equivalent to laws, so if they are to be revoked, a legislative process needs to be initiated.
There are also another 55 orders and announcements that are equivalent to cabinet resolutions, which decrees issued by the cabinet can revoke, he said.
However, Mr Saritpong said that Bhumjaithai believed some of the orders and announcements issued by the NCPO should remain in force as they are still necessary for running national affairs.
"Some of them will look good in the eyes of foreign investors if they change from coup-makers' orders to normal laws," he said.
A party source said the thrust of the bill is to revoke some orders and announcements issued by the NCPO under Section 44 of the interim constitution enacted after the 2014 coup, which are seen as restricting people's rights and freedoms.
The section granted Gen Prayut, as head of the NCPO, sweeping powers to override all other laws. Section 44 was carried over into the current constitution. Section 279 of the charter also endorses NCPO orders and announcements.
