The duo, remanded to 14-days judicial custody by Special Judge Sangita Dhingra Sehgal, also termed the probe as "malicious" and said the Delhi Police, which yesterday gave clean chit to Congress Party and SP, was today examining Singh who was associated with the latter.
"They (police) are saying their investigation is going on and today they are questioning Amar Singh. But yesterday they have themselves given clean chit to the Congress and the Samajwadi Party. It is only an eyewash. As they are saying that, they are also questioning Amar Singh today," Hindustani's counsel Anand said.
He also alleged that police have flouted the court's order regarding presence of defence counsel at the time of the interrogation of the accused in their custody as he was not told about it at all.
"Just now, he (crime branch official) said that both the accused were interrogated. Why were the defence counsel not informed about it despite the court's order?" he asked.
At the outset when the two accused were produced, the judge wanted to know from the police about the outcome of the their custodial interrogation.
"What has been done since yesterday, show me," the judge asked the police.
Responding to the court's query, the police said they have been interrogated "at length" and the probe was going on in a fair manner.
Hindustani and Saxena, arrested for their alleged role in the scam, were interrogated by the Joint Commissioner and other officials and they were confronted with each other and an IAS officer S P Gupta, who is one of the witnesses in the case, the crime branch of the Delhi police said.
The judge asked the police why they have not secured the presence of defence counsel during interrogation of the accused as ordered by the court.
The police countered the allegations of the defence counsel by reiterating their stand that they are doing fair probe in the case.
The defence counsel also contended that the police is doing nothing in the case and their probe is malicious.
Delhi police had yesterday alleged that Hindustani was the "master orchestra" of conspiracy to bribe BJP MPs to vote in favour of Manmohan Singh government in a trust vote in 2008.
