The party said the way the CBI has argued the case, it is nothing but a "blatant" and "open" misuse of country's premiere agency.
It said that for all these days the CBI had been arguing that Shah was a main accused, but it changed its stand and made him "one of the accused" in the case.
"This is nothing, but a blatant misuse of the CBI by the BJP," Yadav said.
Last week, the Aam Aadmi Party accused the CBI of taking a 'U turn' and "weakening" the Sohrabuddin Sheikh fake encounter case.
Addressing a news conference here, party leaders Ashish Khetan and Yogendra Yadav alleged that the CBI was presenting a "wishy washy and weak" case to the court in Mumbai to give Shah an escape route. They added that a battery of Shah's lawyers argued before the court for two days, while a "junior" CBI lawyer presented his case in just 15 minutes.
