Masyumi Party
On 24 March 1956, Moeljatno was selected to be Minister of Justice during the Second Ali Sastroamidjojo Cabinet; his selection was heavily influence by the Masyumi Party. However, he often came into conflict with Prosecutor General Soeprapto over their differing viewpoints on the role of the prosecutor general's office. At the time it was a branch of the Ministry of Justice, having inherited the arrangement from the Dutch colonial system; however, Soeprapto believed that the function of the prosecutor general was half executive and half judicial and as such demanded to be accountable only to the cabinet. As Moeljatno was held responsible for the actions of the prosecution, he pushed to keep the status quo by drafting legislation which explicitly made the prosecutor general subservient to the Minister of Justice. After it was passed by the cabinet in October 1956, Moeljatno received heavy opposition from the police and prosecutor's office. Moeljatno resigned as Minister of Justice on 9 January 1957, and when the cabinet fell in mid-March, the bill was dropped.
