European Court of Human Rights (ECHR)

The provided news articles focus on euthanasia in Spain and marital rights in France. None of them mention the European Court of Human Rights (ECHR). Therefore, it is impossible to provide a summary of the ECHR based on this information. A summary would typically include the ECHR's role as a regional human rights court established by the Council of Europe, its function in hearing complaints about human rights violations, and its impact on member states' laws and practices. However, without relevant content in the provided articles, such a summary cannot be generated.
