After a few years, he became the Chief of Offices of Jakarta High Court and Head of State Attorney of Denpasar in 1962.

Naro and others who originally came from the Parmusi, called themselves as the Muslimin Indonesia (MI) faction in the United Development Party.

[2] Later on, MI became one of the largest faction in the party, frequently conflicting with NU (Nahdlatul Ulama).

[3] Naro's chance to become the chairman of the party widened after the walk out by the NU faction of the PPP during the 1978 General Session of the People's Consultative Assembly.

Naro ensured that none of the party members had an independent source of power, and effectively centralized all of the patronage channels to himself.

[3] During the 1980s, Soeharto prompted political parties to accept Pancasila as its only ideology, creating the concept of single principle.

This concept was first delivered during Soeharto's speech in the Armed Forces meeting on 27 March 1980 and in the Kopassus anniversary on 16 April 1980.

[3] Soedardji demanded Naro to organize an extraordinary muktamar to end the conflict in the party.

Opposing him was Sudharmono, which was nominated by Golkar, and supported officially by the armed forces, regional delegation, and the Indonesian Democratic Party.

[9] Soeharto intervened the discussion about the vice presidency by saying that "the candidate that predicts himself would not obtain majority for the election should withdraw".

Diah explained that Soeharto's statement expects the withdrawal of the said candidate "to give more room to those who certainly elected with the most votes".

The next morning, the PPP fraction sends a letter to the speaker of the MPR that states the withdrawal of Naro's candidacy for the position of Vice President.

It was the only time in the history of the New Order a dissent occurred on the election of vice president post, and broke the Soehartoist concept of "deliberation to reach consensus".
