Mrs López Ostra lived 12 metres from a waste treatment plant that emitted fumes, smells and noise causing health problems and nuisance. Despite complaints, Spanish authorities failed to adequately address the pollution. The ECtHR held Spain violated Article 8, establishing that severe environmental pollution can breach the right to private and family life.
Facts
Mrs Gregoria López Ostra lived with her family in Lorca, Spain, approximately 12 metres from a waste treatment plant built on municipal land with State subsidies to treat waste from local tanneries. The plant began operating in July 1988 without the required municipal licence. Its malfunction released gas fumes, pestilential smells and contamination, causing health problems to local residents. The town council evacuated affected residents for three months, and in September 1988 ordered partial cessation of activities, but nuisances continued.
Domestic Proceedings
Mrs López Ostra applied for protection of fundamental rights in October 1988. The Murcia Audiencia Territorial acknowledged the nuisance impaired quality of life but found it insufficient to infringe fundamental rights. The Supreme Court dismissed her appeal, and the Constitutional Court ruled her appeal inadmissible. Medical evidence showed her daughter suffered health problems linked to the pollution. The family eventually moved in February 1992 and purchased a new house in February 1993.
Issues
The principal issues were whether Spain violated Article 8 (right to respect for private and family life and home) and Article 3 (prohibition of degrading treatment) of the European Convention on Human Rights through the authorities’ failure to address the environmental pollution affecting the applicant.
Judgment
Article 8
The Court established an important principle regarding environmental protection and private life:
Naturally, severe environmental pollution may affect individuals’ well-being and prevent them from enjoying their homes in such a way as to affect their private and family life adversely, without, however, seriously endangering their health.
The Court addressed the balance between competing interests:
Whether the question is analysed in terms of a positive duty on the State – to take reasonable and appropriate measures to secure the applicant’s rights under paragraph 1 of Article 8 -, as the applicant wishes in her case, or in terms of an ‘interference by a public authority’ to be justified in accordance with paragraph 2, the applicable principles are broadly similar. In both contexts regard must be had to the fair balance that has to be struck between the competing interests of the individual and of the community as a whole.
The Court found that despite the margin of appreciation:
the State did not succeed in striking a fair balance between the interest of the town’s economic well-being – that of having a waste-treatment plant – and the applicant’s effective enjoyment of her right to respect for her home and her private and family life.
Article 3
The Court found the conditions, though very difficult, did not amount to degrading treatment within the meaning of Article 3.
Implications
This landmark case established that States have positive obligations under Article 8 to protect individuals from severe environmental pollution, even where such pollution does not seriously endanger health. It confirmed that the right to respect for home and private life extends to environmental protection. The judgment set a precedent for subsequent environmental human rights cases and demonstrated that economic interests must be balanced against individuals’ Convention rights. The case significantly expanded the scope of Article 8 protection in environmental contexts.
Verdict: The Court unanimously dismissed the Government’s preliminary objections, held there was a breach of Article 8 of the Convention, held there was no breach of Article 3, and ordered Spain to pay the applicant 4,000,000 pesetas for damage and 1,500,000 pesetas (less 9,700 French francs) for costs and expenses.
