MH370 A family member of one of the passengers on the missing Malaysia Airlines (MAS) flight MH370 will file a lawsuit against the carrier and the government over the incident.

The law firm representing the victim’s family, Rusmah Arunan & Associates, said the suit will be filed at the Registry of the High Court in Kuala Lumpur tomorrow.

The suit cites negligence in the investigation of the incident on the part of MAS, the Department of Civil Aviation, Department of Immigration, Royal Malaysian Air Force and the Malaysian government.

The suit is being filed on behalf of the next of kin of passenger Jee Jing Hang, including his two underaged children, who have been left clueless since the flight disappeared some eight months ago.

The lawsuit also blamed the prime minister for abruptly concluding the investigation into the missing MH370 by stating that the aircraft “ended in the southern Indian Ocean”.

The law firm in a statement today said: “Such a statement from the prime minister is indeed a strong conclusion and indication. The PM made this statement in the face of the information available to him.”

Despite eight months having passed since the flight vanished, the firm claims that no proper answer had been given to the families of the victims.

"So many questions are left unanswered, so many theories have been uttered and opinions (warranted and unwarranted) are uttered. These have caused nothing but anguish, doubts and misery to them.”

The firm added that its clients (Jee’s family) have decided to go ahead with the lawsuit after being counselled by lawyers and experts.

"We have spoken to various experts relating to this industry. Having carefully analysed and weighed their expert opinions, we believe that our clients have sufficient grounds in establishing such a case against the named parties," Rusmah Arunan & Associates said.

Flight MH370, which was carrying 239 people on board from KL International Airport to Beijing, China, went missing on March 8 after departing the airport about 12.30am.

The flight, which was scheduled to land in Beijing at 6.30am, was declared missing after the air control tower lost communication with it.

Of the the people lost with the Boeing 777-200ER aircraft, 152 are from China and 50 from Malaysia. The two nationalities make up the bulk of those who went missing on the flight.

At a press conference 17 days later, Prime Minister Najib Abdul Razak said investigations have confirmed that the plane went down in the Indian Ocean.

Till today, no wreckage or body has been found despite it being more than eight months since the flight vanished into thin air.
