Having come to strongly oppose Sukarno, Princen initially placed some hopes in
Suharto, who overthrew him in the
Transition to the New Order following the 1965 attempted coup d'état of the
30 September Movement and whose coming to power had the incidental effect of getting Princen released from prison after four years. The Suharto regime proved both extremely brutal and highly corrupt: "My opinion of Mr. Suharto changed at the moment he started gathering as much money as he could for himself." In the late 1960s, Princen was a correspondent for Netherlands Radio and several Dutch newspapers. This was directly connected with his work as a human rights activist, in which he was to spend most of his time and energy for the remainder of his life. In 1966 Princen founded and headed Lembaga Pembela Hak-Hak Azasi Manusia (Indonesian Institute for the Defense of Human Rights). It was the first human rights organization in Indonesia, and which handled many high-profile cases during the years of the Suharto dictatorship and provide a reliable alternate source of news to Western journalists in Jakarta. Among the earlier campaigns which Princen conducted was on behalf of the left-wing writer
Pramoedya Ananta Toer, imprisoned and tortured by the Suharto regime. At the end of 1969 he published, jointly with the journalist Jopie Lasut, an extensive report on the mass murder of Communist sympathizers at
Purwodadi in Middle Java – for which Princen and Lasut were arrested and interrogated. This was followed in the early 1970s by Princen's prominent role in creating a larger organization, the Indonesian Legal Aid Institute (LBHI), where he met with many other human rights figures including
Adnan Buyung Nasution, Frans Winarta,
Besar Mertokusumo,
Yap Thiam Hien, Victor D. Sibarani,
Mochtar Lubis,
Albert Hasibuan and members of the younger generation of activists. The eulogy published after his death by the Indonesian oppositional news and commentary website Laksamana. Net noted that
Prisoner again, labor advocate, political reformer As under Sukarno, Princen was jailed several times under Suharto – mainly on charges of organizing illegal political protests. In January 1974, the visit of the Japanese Prime Minister
Tanaka Kakuei led to riots in Jakarta. Ostensibly fuelled by resentment of Japanese exploitation of Indonesia's economy, and to start with possibly encouraged tacitly by some Army commanders, this so-called "
Malari Affair" escalated and came to express repressed resentment about the growing gap between rich and poor in Indonesian society and the bureaucratic capitalists connected with the regime. Involved as an outspoken human rights activist, Princen was imprisoned, where he spent the next two years (1974–1976). In early 1990 Princen had a major role in founding the Merdeka Labor Union (Serikat Buruh Merdeka – "
Merdeka" means "Independence") – together with
Dita Indah Sari, an Indonesian labor activist and
Amnesty International Prisoner of Conscience. He conducted extensive correspondence with the
International Labour Organization (ILO) regarding the conditions of Indonesian workers. Max White, Princen's friend and coworker, stated that "Poncke believed that 'Labor rights are human rights', he saw no distinction". In the early 1990s, he was a founding member of the
Petition of Fifty, a movement for democratic reform which included conservative military figures who had fallen out with Suharto and which for the first time in decades raised a real challenge to his rule. Along with other members of the group including
Ali Sadikin and
Hoegeng, Princen again found himself persona non-grata with the regime, although he joked to his visitors that by that time he was "too old to put in jail again". In 1992 he won the Yap Thiam Hien Human Rights Award – named for the
Chinese Indonesian lawyer
Yap Thiam Hien, a fellow human rights activist. In 1996 he was involved in protests against Suharto's crackdown on the
Indonesian Democratic Party (PRD). Visiting delegations of international human rights organizations at the time found him "a source of accurate information about those who were attacked at the PRD headquarters". Much of his time in the following years was spent in writing open letters to President Suharto, on such issues as demanding the abolition of extrajudicial bodies, asking for answers about "disappearances" in
East Timor (and in the capital Jakarta itself), and affirming that political change needed to take place before the Indonesian economy could recover. His once-isolated legal aid organization had become part of a large and growing network of NGOs working for political and social change. He became known as "the man in the wheelchair at political rallies, who is rarely absent from a courtroom during political trials, and at mention of whose name students around the country were smiling with admiration. ==Princen and East Timor==
