In July 1951, Iskaq agreed with the DPV (a Dutch tobacco plantation company based in North Sumatra) to return half of its plantation (130,000 out of 255,000 hectares), which had by now been occupied by local farmers. While Sukiman's ministry did not act much on this agreement, the Wilopo Cabinet's attempt to enforce the agreement resulted in clashes between the farmers and police in Tanjung Morawa, with five people killed. Regarding Acehnese autonomy, Iskaq attempted to assert central government authority by transferring administration some areas to East Sumatra and Tapanuli, replacing a number of officials, and in March 1952 terminating the governorship of Daud Beureu'eh. Following the fall of the Sukiman Cabinet, the ensuing PNI-Masyumi Wilopo Cabinet did not include Iskaq due to Masyumi objections, and he was replaced by Mohammad Roem.
