Students and oppositional leader In 1992, Prinya was the secretary-general of the Students Federation of Thailand. He joined the Confederation for Democracy (CFD), an oppositional alliance against the military-sponsored government of General Suchinda Kraprayoon. He became a key figure of the network, alongside Palang Dharma Party leader Chamlong Srimuang, slum-dwellers' activist Prateep Ungsongtham, the daughter of incarcerated activist Chalard Worachat, trade unionist Somsak Kosaisuuk and the academics Sant Hathirat and Weng Tojirakarn.

Academic career Prinya continued his studies in Germany, receiving his master's degree from the University of Göttingen in 1998 and his Ph.D. from the same university in 2004. His dissertation thesis compared the systems and problematics of party financing, donations, transparency and control in Thailand and Germany.

Proposals for constitutional reform Prinya has made several proposals for reform of the Constitution of Thailand. These include the eliminating of the requirement that candidates for the House of Representatives must be members of a political party for at least 90 days prior to an election. The requirement was originally designed to increase the affiliation that politicians have for political parties, thus increasing the strength of party-based politics. Prinya made the suggestion during the Thailand political crisis 2005-2006, during which there was growing public pressure to allow Thai Rak Thai politicians to more easily defect from their party.Public Relations Department of Thailand, Judges call for EC to step aside

Prinya also criticized the concept of multi-seat constituencies, noting that the system was based on population and not on the equality of people. With multi-seat constituencies, "Some provinces, such as Ranong, which has a lower population than other provinces, would get only one MP, but constituencies in larger provinces like Nakhon Ratchasima would get three MPs," he said.The Nation, Academics oppose multi-seat idea, 11 March 2007
