K. Sukumaran led an inquiry for the Indian People's Tribunal (IPT), visited the rehabilitation sites, and on 2 May 1999 delivered an interim report to the government, which accepted that in principle the demolitions were not legal.

After acknowledging that some high courts were corrupt, he said "I am pained by the dirt being flung at the judiciary because I have great respect and admiration for its edifice.
