Grubb & Ellis Co. is asking a bankruptcy judge to allow workers who were hurt during the cleanup of lower Manhattan after the Sept. 11, 2001, attacks to pursue their lawsuits against the company and seek damages from its insurers, the Wall Street Journal reported on Saturday. The commercial real estate broker is asking the judge to sign off on a deal reached with lawyers representing many victims in the cases, which were halted as a result of Grubb & Ellis's chapter 11 filing. The multiple lawsuits involve at least 490 victims who were involved in clearing debris after the attacks. Grubb & Ellis is named as a defendant in the cases where the plaintiffs suffered mainly respiratory injuries after the attack, outside the World Trade Center area or within the World Trade Center site.
