The anti-government, nationalist " Yellow Shirt" on Tuesday petitioned the government, calling them to defy the pending ruling of the International Court of Justice ( ICJ) on the contested land surrounding the ancient Hindu Preah Vihear temple over Thai and Cambodian ownership.

Panthep Puapongpan, the spokesperson of the yellow-shirted People's Alliance for Democracy (PAD), said that the PAD urged the government to display its stance against the ICJ judgement and jurisdiction, and refuse to sign any agreement as a result of the court's order.

About a hundred of PAD activists show up at the government house to show its support for the PAD's demand.

Thailand and Cambodia are scheduled to give their oral statements on the dispute to the ICJ at The Hague, Netherlands, on April 15-19.

"It is not necessary to follow the ICJ's injunction," the PAD spokesperson said. He added that the PAD is now to wait and see before taking any action further.

In 2010 and 2011, the PAD held months-long demonstrations related to the disputed area both in Bangkok and near the disputed border area.

"If the government follows the ICJ's order, it is tantamount to intentionally let go of the Thai territory," Thai News Agency quoted the spokesperson as saying.

The petition comprises seven demands. Some of them are that the Thai government should state that the ICJ has no legitimacy to rule over the dispute, the government should stop using its press team, assigned to publicize news on the issue from government's views, and allow public and private media to publicize the issue from their views and the government should help the two PAD activists who were jailed in Cambodia for illegally entering Cambodian border while they were on a trip to explore the undemacrated area in 2010.

Last week, Thai Foreign Minister Surapong Tovichakchaikul said that it is possible that the ICJ's ruling may not end in Thailand' s favor.

Meanwhile, Deputy Prime Minister Phongthep Thepkanchana said the Thai legal team will meet with foreign legal consultants in London next month to prepare the oral statement for presentation to the Court on April 19.

The legal consultants have been given full authority in fighting the case for Thailand's ultimate interests, said Phongthep, appointed by the premier to supervise the case. He is also education minister.

The government welcomes suggestions from the Thai people and any organizations concerning the case but final decision depends on the judges, he said, warning against creating negative attitudes towards Thailand, the minister said.

"Judges are human beings. Their negative attitudes will be unfavorable to Thailand," Thai News Agency quoted Phongthep as saying.

In its 1962 verdict, the ICJ only ruled that the temple belonged to Cambodia but there was no judgement on the 4.6 square kilometers of the land surrounding the temple.

The dispute between the two countries erupted again shortly after the United Nations Educational, Scientific and Cultural Organization (UNESCO) approved Cambodia's bid to have the temple named a World Heritage Site in 2008.
