"We make it clear that M L Sharma is entitled to summon any person in the inquiry," a special bench of Justices M B Lokur, Kurian Joseph and A K Sikri said and also ordered that he will have access to all documents required by him for his probe.
The bench, which asked the former CBI officer to submit the report of inquiry in three months, accepted his requirement of three retired police officers and two support staff for carrying the job entrusted to him.
The bench said it will fix the remuneration for Sharma and others on November 16 after knowing the exact nature of work likely to be done by them, as Sharma himself has declined to make any demand.
A letter written by Sharma to the Attorney General about the names of officers and secretarial staff required by him was taken on record after all sides agreed to his proposal.
