Bandra police, who investigated the case, had written to RTOs in suburban Andheri and Wadala and the Excise Department seeking information as to whether the Bollywood actor held a driving licence and a liquor permit.
The police's letters and respective replies were submitted by Special Public Prosecutor Pradeep Gharat before judge D W Deshpande.
Their value as evidence would be decided at the time of final arguments, said the judge.
Khan is charged with ramming his car into a bakery in suburban Bandra on September 28, 2002, killing one person and injuring four who were sleeping on the pavement. He was drunk at the time, according to the police.
The replies of RTO and Excise authorities are important as they declare that Khan had liquor outside his house without a permit and then driven his SUV when he did not even have a driving license.
The lawyer said he would like to cross-examine Kadam as Khan's bodyguard, constable Ravindra Patil, the eye-witness to the mishap, is no more.
The prosecution objected, saying that the accused's lawyer had had enough opportunity to cross-examine Kadam.
The judge asked Gharat to file a written reply to the application on the next date, March 24.
