In 2013, over 700 Chileans filed a claim against Boliden Mineral in Swedish court. Plaintiffs alleged they have suffered health problems as a result of Boliden's dumping smelter sludge near their town. In 2018, the Swedish court ruled in favour of Boliden.

Factual background

Boliden shipped approximately 20,000 tonnes of smelter sludge to the Polygono area in Arica between 1984 and 1985. The waste derived from Boliden’s Rönnskär arsenic plant in Sweden and was sold to a Chilean company, Promel, for processing. However, the waste was reportedly left unprocessed and unprotected at the site until 1998. Starting in 1989, housing developments were built nearby, but Chilean authorities concluded in 2009 that the area should be evacuated as it remained contaminated.

Legal argument

In September 2013, Arica Victims KB, a company representing 707 Chileans, filed a claim against Boliden Mineral, a Swedish mining company, at the county court of Skellefteå, Sweden. The claim alleges that Chileans from Arica have suffered health problems as a result of the dumping of Boliden’s smelter sludge near the town in the 1980s. The plaintiffs have requested SEK 90 million in damages, plus interest.

The plaintiffs allege that, since the 1990s, the community has suffered from serious diseases, including cancer, miscarriages, skin conditions and breathing problems. Medical tests showed excessive levels of arsenic in the residents’ blood. The plaintiffs allege that Boliden acted negligently. The plaintiffs also state that there is evidence that Boliden knew that the sludge would pose a significant health threat. Boliden had submitted a patent application, prior to the waste dumping, for a new technology to remove arsenic from sludge. In that application, Boliden stated that their technology was the only technology that could make the waste safe.

Legal proceedings

Boliden filed its defence on 20 January 2014 and denied the claim in its entirety. It argued that it did not act negligently and that it could not have foreseen the events that led to the health problems. It further suggested that it is “improbable” that it was Boliden’s waste that caused the arsenic levels recorded in residents’ blood. Boliden argues that the Chilean health authority and Promel are responsible for the health issues suffered. In support of its argument, it cites a 2007 case, in which the Chilean Supreme Court held that the state had to compensate 365 residents from the Arica area, as a result of health problems caused by toxic waste. In the 2007 Chilean case, Promel was unable to pay any compensation as it had ceased to exist by the time of the judgement. The state was found liable for having not implemented protective measures in relation to the toxic material that Promel had been storing.

In October 2017, the District Court in Skellefteå, Sweden began hearing oral arguments.  On 8 March 2018, the Court ruled in favour of Boliden, dismissing the plaintiffs' compensation claim.  Plaintiffs are likely to appeal the decision.
