A petitioner's lawyer has questioned the investigation into the Zubeen Garg case, citing alleged lapses by the Special Investigation Team (SIT). The lawyer claims crucial evidence was not collected from Singapore, basic case documents were withheld from petitioners, and the current chargesheet is weak, citing only a water bottle as evidence. He suggested that evidence could be obtained from Singapore via the Mutual Legal Assistance Treaty (MLAT) to strengthen the prosecution's case for criminal conspiracy.
