Hinshaw & Culbertson is facing allegations of negligence following its work representing an insurer and a doctor in a malpractice suit filed in Florida state court.

Dr. Anthony Battillo, a former chiropractor and the plaintiff in the negligence lawsuit, was sued in 2010 for malpractice after his client allegedly sustained injuries during an appointment with him. The malpractice suit, filed Tuesday, claims that lawyers at Hinshaw & Culbertson received an offer to settle for $1 million in 2014, but instead Battillo was hit with a judgment of more than $3 million about four years later.
