Final answer:
Until 1998, violations of the European Convention on Human Rights were addressed through legal proceedings and judgments by the European Court of Human Rights.
Step-by-step explanation:
Until 1998, violations of the European Convention on Human Rights (ECHR) were treated differently depending on the specific violation. However, the establishment of the European Court of Human Rights (ECHR) in 1959 provided a means for individuals and groups to bring cases alleging ECHR violations. The ECHR is responsible for interpreting and applying the ECHR and has the power to make binding judgments against member states that violate the rights protected under the convention. Therefore, violations of the ECHR were addressed through legal proceedings and judgments by the ECtHR.
