The first draft of the charter is now complete and it will be debated by the National Reform Council from April 20 to 26.
The country will get its first chance to see the entire draft charter - all 315 sections - on April 27.
Borwornsak Uwanno, chairman of the Constitution Drafting Committee (CDC) is pleased the draft charter was finished in line with the deadline set under the political roadmap.
But it will be an uphill task to familiarise the people with the new and complex charter, let alone have it accepted by the international community.
During the four-month drafting period, the draft charter has come under fierce criticism from all fronts, including every political party.
Big questions hang over the sources eligible for prime ministership - either an elected MP or non-elected person - the mixed member proportional representation (MMP) system and the indirect election of senators. The charter drafters must be ready to give the answers.
Mr Bowornsak, however, remains confident the public will find the draft charter satisfactory because it has strengthened civic power to ensure that politics respond to people's needs to clean up money politics, restore normalcy, and carry on with reform programmes to bridge economic disparity and achieve political reconciliation.
National reform remains the common mission of the National Council for Peace and Order (NCPO), National Legislative Assembly (NLA), the cabinet, the National Reform Council (NRC) and the CDC, he insisted.
It is no secret that many NRC members are not happy with the draft charter and they are ready to blast it.
The draft charter is now only half-way through its journey and the challenges it is likely to face.
On Aug 6, the NRC will vote whether to endorse the draft charter. That is when we will know for certain what the new charter will look like.
While CDC spokesman Khamnoon Sitthisamarn said the CDC will be open to suggestions from the NRC, it can't be denied that the most important suggestions will come from NCPO and the government.
It is them which will ultimately decide the direction of the new charter.
It is most certain the NRC will take the charter drafters to task for being open to a non-elected prime minister as well as the new election system for MPs and senators which will weaken the new government.
"We have to be prepared to answer their questions," said Mr Khamnoon.
"The focus of debates will be on how we choose the PM, MPs and senators. The new dimensions of the draft charter which strengthen civic forces, unfortunately, will not receive due attention."
What is important for the draft charter is to make real change happen, he said. "The charter shouldn't just be a sanctified document put on an altar."
What distinguishes this charter from the previous one is its special segment containing 21 sections on reform and reconciliation, said Mr Khamnoon.
These mechanisms will ensure the reform process will continue under the next government, he added.
All eyes are on what "suggestions" NPCO and the Prayut government will have for the draft charter.
So far, Prime Minister Prayut Chan-o-cha has not dropped any hints as to what changes he wants.
"He only said it's not time, that it's too soon to make any comments," said Mr Kamnoon.
PM Prayut said on his TV programme last Friday that he admires the hard work of both the CDC and the NRC, which in his view do not deserve to be criticised so severely.
He also cautioned against a new round of conflicts stemming from the new charter.
Thais must ask themselves if they want reform to happen, or if they want to see the country drowned in protracted political conflicts yet again.
He also asked the public to accept changes introduced in the draft charter.
Going back to previous charters would only bring back the same political problems, he said.
This is an important statement from the most powerful man in the country.
From now on, his every word on the draft charter will be closely watched as CDC members cross their fingers that it will have the PM's support till the very end.
