Campesinos successful in preliminary issues trial against oil company Amerisur

A group of Colombian farmers have won both arguments put forward in a preliminary issue trial in their ongoing case against Amerisur Resources Limited. The High Court has ruled today that there is no bar to the imposition of liability against a multinational parent company under Colombian Law and that the claims are not time-barred.

Posted on 26 January 2023

The preliminary issues trial was heard in the High Court in London between 11 and 15 July 2022. The case is brought by 171 individuals, mainly small-scale farmers and their families (known as campesinos), against Amerisur which is owned by Geopark, a large oil and gas company listed on the New York Stock Exchange. 
ThE High Court has dismissed Amerisur’s argument that the campesinos claims are time-barred and should be dismissed without the court even hearing their substantive claims of environmental contamination.  The court also dismissed Amerisur’s argument that, as a parent company, it cannot be liable under Colombian law for the harm allegedly caused by its operations in Colombia.  
Amerisur is an English company whose main business activity is on-shore oil exploration and extraction in Colombia. The environmental pollution case is being brought under Colombian law but will be heard by the courts in England because the company falls under the jurisdiction of the courts in England and Wales.
The case will now progress to a substantive trial of the issues at a later date.
The campesinos, represented by law firm Leigh Day, allege in their case against the British company that an oil spill in 2015 contaminated their local waterways on which they were reliant for drinking, bathing, fishing and other basic needs. The oil spill occurred during an attack by an armed group on five tankers containing Amerisur’s crude oil where the drivers were forced to dump their loads leading to large amounts of oil spilling into the streams and wetlands. The campesinos argue that the spill and serious failures and delays in the clean-up caused significant damage to the local environment in the Putumayo region, which is part of the Amazon rainforest, and has caused harm to their livelihoods. There is strict liability under Colombian law for harm arising from dangerous activities. The campesino’s argue that the attack was foreseeable and preventable and that Amerisur is liable despite the involvement of the armed group. 
The campesinos were successful in securing a freezing injunction against Amerisur in January 2020 which required the company to preserve around £3million of its UK assets ahead of the £240million sale of Amerisur to GeoParkColombia.
The claimants are members of remote communities living in southern Colombia in Putumayo, near the Ecuadorian border. The waterways in the area were used for drinking water, bathing and fishing. 
The region has continually been in a state of heightened security and community activists opposed to oil exploration have been subject to death threats. 
Richard Meeran, head of the international team at Leigh Day, said:
“This oil spill which our clients say is the legal responsibility of Amerisur, and the woefully inadequate clean-up, have caused damage not only to our clients’ livelihoods but also to the natural environment which forms part of the Amazon, an internationally recognised area of huge natural importance. This case is yet another stark example of the harms being caused to the environment by the use of oil around the world.”
