The group, comprising academics and intellectuals based in Chiang Mai, made the declaration at Thammasat University amid growing concerns about how the new military-directed constitution will look.

"In the past, all constitutions were drafted by the elite and addressed only certain classes in society rather than society as a whole," university rector Somkiat Tangnamo said. "Though it's easy to tear up a constitution in Thailand through extra-legal means, we can't live without one for long."

Somkiat warned that without genuine public participation in the drafting, the charter was doomed to fail. "It can be predicted now that the new constitution will only end up being temporary."

The declaration was read on the Pridi Banomyong Lawn of Thammasat University, a symbolic place as Pridi led a revolt which ended absolute monarchy and introduced the first Thai constitution some seven decades ago. The three other principles are the right to belong to a union, the right of citizens to promulgate law and the right to local self-administration.

"All six principles must be enshrined in the [18th] constitution in order to bring about equality and security amongst citizens," the group said.

It said the constitution cannot just be about setting rules for politicians.
