New York City on Friday asked a Manhattan Supreme Court judge to order Con Ed to pay its legal fees and take over the defense of nearly 60 lawsuits stemming from a deadly gas explosion in 2014.

In a 13-page complaint, the city Law Department argued that Consolidated Edison Co. of New York was ignoring its obligations to defend the lawsuits under a series of permits it received from the city Department of Transportation in 2011 to perform work at the ill-fated East Harlem work site.
