"It is an attack on the nation, and it is the Centre's responsibility to protect the nation," argued advocate V P Patil, the petitioner, in the court on Friday.
At least 27 persons were killed and scores of others injured in the explosions at Dadar, Zavari Bazaar and Opera House areas. The Maharashtra Anti-Terrorism Squad is probing the serial blasts, but no arrests have been made till now.
Patil pointed out that the probe into the blast near Delhi High Court, which took place on September 7, had already been handed over to the NIA. "There has been no progress in the probe (of Mumbai case)," he maintained.
While asking the Maharashtra government to file a reply to the PIL, a Division Bench of Justices Sharad Bobde and V K Tahilramani, however, seemed to disagree with the petitioner's contention.
"Prima facie, we are not inclined to accept your argument," Justice Bobde maintained. "We can not assume that Anti-Terrorism Squad is not competent, or that there is no coordination between (central and state) agencies," he said.
When Patil mentioned about NIA taking over the Delhi HC blast probe, the Judge said, "Delhi is the national capital..." Advocate Patil promptly said, "Mumbai is the commercial capital".
The hearing was adjourned for a week.
