Talk about an interesting lawsuit!

Zurich American Insurance Co. has filed suit against a Sony Corp. division, claiming they do not have the duty to cover the cost of lawsuits and related expenses associated with the hacking of Sony's PlayStation Network.

The lawsuit was filed July 20 in New York State Supreme Court in Manhattan. The suit states Zurich is not mandated to “defend and potentially indemnify” Sony from class action suits, other related claims and costs associated with legal investigations concerning the April hacking incidents.

The court documents state Zurich officials believe the insurer is not required to defend or indemnify Sony. Zurich says Sony’s primary commercial general liability and excess policies do not qualify for such coverage against these types of losses.

Zurich also claims Sony's other insurers should be liable for providing primary coverage for these losses. Those carriers include: Mitsui Sumitomo Insurance Co. of America; National Union Fire Insurance Co.; and ACE American Insurance Co.

Sony’s PlayStation Network was hacked in April, 2011, exposing over 100 million customer accounts and their private information. The incident, which was reportedly the second-largest Internet breach in U.S. history with losses up to $2 billion, has resulted in a flurry of claims against Sony.
