A division bench of Chief Justice Kalyan Jyoti Sengupta and Justice P V Sanjay Kumar posted the matter to April 24 after they were informed that the FSL report pertaining to firearms used by police in the incident was still awaited.
Additional Advocate General D Srinivas said that the report on viscera of the 20 people is still awaited.
The state government had on Monday submitted to the High Court the first postmortem report of the 20 people killed in the firing.
The High Court had last week ordered fresh autopsies of six victims of the police firing in Seshachalam forests.
Accordingly, a team of doctors from Osmania Medical College here had conducted re-postmortem of the six bodies in Tamil Nadu.
Twenty people were gunned down in Seshachalam hill ranges of Chittoor district in Andhra Pradesh on April 7 in an operation by the police.
In her complaint with Chandragiri police in Chittoor, Muniyammal alleged that "it was not an encounter death (as claimed by the police) but was a well-planned and organised crime, committed by the STF (special task force of police)."
Subsequently, based on her complaint, AP police registered an FIR under sections 302 (murder) and 364 (kidnapping or abducting in order to murder) against "unknown" STF personnel.
