The Constitution Drafting Committee (CDC) has agreed to trim down the draft charter, with more than 100 provisions targeted for change.
CDC spokesman Kamnoon Sidhisamarn revealed on Tuesday the CDC had agreed to ''back off'' from 10 key issues in the draft charter.
The committee will begin rewriting the document from Thursday based on recommendations from various parties including the cabinet and the National Reform Council (NRC).
The CDC on Tuesday held another closed-door meeting to consider changes to charter provisions on reform and reconciliation proposed by the cabinet.
One proposal calls for the merger of a national reconciliation committee and a national reform strategy committee, both of which will be set up under the new charter, Mr Kamnoon said.
The cabinet also suggested that only pressing national reform issues be included in the new charter, while other minor issues should be included in the organic laws linked to the new charter, Mr Kamnoon said.
The cabinet also wanted the CDC to clarify whether a provision to set up a national reform steering assembly under the new permanent charter will become redundant as another body using the same name will also be established under the interim charter.
Questions have been raised about whether the two bodies will duplicate each other, and the CDC should define the roles of each to avoid confusion, Mr Kamnoon said.
The provision says a national reform steering assembly will be set up under the new permanent charter to oversee reform.
The other body using the same name will also be set up under the interim charter to replace the NRC, which will be disbanded after it votes on the draft charter. The dissolution of the NRC is one of seven amendments of the charter, submitted by the cabinet and the National Council for Peace and Order (NCPO).
Replacing the NRC, a national reform steering assembly will be set up with 200 members appointed by the prime minister to give advice on national reform. The proposed seven amendments passed the National Legislative Assembly in three straight readings last week.
CDC member Anek Laothammathat said the CDC is expected to combine about 15 draft charter provisions regarding reforms into one single provision in a bid to curtail some redundant provisions.
Deputy Prime Minister Wissanu Krea-ngam welcomed the CDC's move to make changes to the draft charter, saying the move was a good sign.
Also on Tuesday, CDC chairman Borwornsak Uwanno received a letter from consumer protection groups, which have called on the committee to keep intact a charter provision on the creation of an independent consumer protection body.
The letter came after the cabinet proposed the provision be cut. However, Mr Borwornsak said it was up to the CDC to make a decision.
