THE HAGUE (Reuters) - A Dutch court ruled on Wednesday that Royal Dutch Shell's Nigerian subsidiary was responsible for oil pollution in the Niger Delta and ordered it to pay damages, saying it should have prevented sabotage at one of its facilities.

The district court in The Hague said Shell Petroleum Development Company of Nigeria Ltd. (SPDC), a wholly-owned subsidiary, must compensate one farmer, but dismissed four other claims filed against the Dutch parent company.

Four Nigerians and campaign group Friends of the Earth filed the suit in 2008 in the Netherlands, where Shell has its global headquarters, seeking reparations for lost income from contaminated land and waterways in the Niger Delta region, the heart of the Nigerian oil industry.

The case was seen by environmental activists as a test for holding multinational companies responsible for alleged offences at foreign subsidiaries, but Shell said it would not set a precedent because the parent company was not held responsible.

The farmer who won compensation, 52-year-old father of 12 Friday Akpan, said he was very happy with the judgment.

"I am not surprised at the decision because there was divine intervention in the court. The spill damaged 47 fishing ponds, killed all the fish and rendered the ponds useless. I had loaned the money from the agriculture loans board and had no way to pay it back," he told Reuters in the Niger Delta city of Port Harcourt.

"Since then I have been living by God's grace and on the help of good Samaritans. I think this will be a lesson for Shell and they will know not to damage people's livelihoods."

Friends of the Earth spokesman Geert Ritsema said they would appeal against the acquittals "because there is still a lot of oil lying around. These sites need to be cleaned."

SABOTAGE BLAMED

The court backed Shell's argument that the spills were caused by sabotage and not poor maintenance of its facilities, as had been argued by the Nigerians.

Ritsema said it was a breakthrough that an oil company was being held responsible for failing to prevent sabotage.

There were 198 oil spills at Shell facilities in the Niger Delta last year, releasing around 26,000 barrels of oil, according to data from the company. The firm says 161 of these spills were caused by sabotage or theft, while 37 incidents were caused by operational failure. Local communities say Shell under reports the amount of barrels spilled.

People who live in the Niger Delta region say their land, water and fisheries have been blighted for years by oil pollution and activists have called for oil companies in Nigeria to be held to the same standard as elsewhere in the world.

A United Nations report in 2011 on the Ogoniland region in the Niger Delta criticized Shell and other multinationals, and the Nigerian government, for 50 years of oil pollution.

It said the area, where Shell no longer operates, needed the world's biggest-ever oil clean-up, which would take 25 years and cost an initial $1 billion.

A decade of militancy by armed groups in the Niger Delta, which had its origins in local anger over oil pollution, shut down nearly half of Nigeria's oil output until an amnesty in 2009. The delta is home to about 31 million people.

COMPENSATION TO BE NEGOTIATED

"We will pay compensation. We didn't lose the case. It was not operational failure. The leak was the consequence of sabotage," Allard Castelein, Royal Dutch Shell's vice president for environment, said in comments after the verdict was read.

"Shell Nigeria should and could have prevented this sabotage in an easy way," the ruling said. "This is why the district court has sentenced Shell Nigeria to pay damages to the Nigerian plaintiff."

Castelein said Shell will negotiate the amount of damages with the farmer, but that an appeal could postpone the outcome of those talks.

The Nigerians - fishermen and farmers - said they could no longer feed their families because the region had been polluted by oil from Shell's pipelines and production facilities.

The pollution is a result of oil spills in 2004, 2005 and 2007, they said.

It is the first time a Dutch-registered company has been sued in a domestic court for offences allegedly carried out by a foreign subsidiary.

The suit targeted Shell's parent company in the Netherlands and its Nigerian subsidiary, which operates a joint venture between the Nigerian National Petroleum Corporation, Shell, Total E&P Nigeria Limited and Nigerian Agip Oil Company Limited.

Shell Nigeria is the largest oil and gas company in Nigeria, Africa's top energy producer, with an output of more than 1 million barrels of oil or equivalent per day.

In October, Shell lawyers said the company has played its part in cleaning up the Delta, which accounts for more than 50 percent of Nigeria's oil exports.
