A former vice president of South Korea's top airline, Korean Air Lines Co., has asked a U.S. court to dismiss another civil lawsuit filed by one of the crew members involved in last year's "nut rage" incident, legal sources said Thursday.

In late July, Korean Air purser Park Chang-jin lodged a suit against his former boss, Cho Hyun-ah, in the Supreme Court of the State of New York for damages caused by the incident.

Cho's legal team requested that the U.S. court dismiss the case, arguing that it should be handled by a court in South Korea, home to both the plaintiff and defendant, for practical reasons.

Moreover, the legal team said that Park is fully capable of receiving compensation in his home country without having to reach out to overseas courts.

"(Park) has already demonstrated that it is possible for him to seek compensation in South Korea," one of Cho's legal representatives said, adding that Park is already taking time off from work after his case was recognized as an industrial accident last month by a local labor welfare agency.

On Dec. 5, Cho forced a Korean Air flight departing from New York back to the gate because of the way her nuts were served -- in an unopened bag instead of on a plate -- and had Park disembark from the plane.

The latest dismissal request is the second one filed by the former executive of Korean Air. Earlier in July, her legal team took similar countermeasures against a suit filed by another crew member to whom Cho had lashed out on during the in-flight commotion.

Both plaintiffs are required to provide a response to the court by mid-September.

In June, the Seoul High Court sentenced Cho to 10 months in prison but suspended the term for two years for changing the aircraft's flight route at the time when she forced Park off the plane.

Prosecutors said they have submitted an appeal to have the court's decision reversed. (Yonhap)
