Here is a useful summary from RTE, the Irish national broadcaster, of what the ECHR court case is about:
'The European Court of Human Rights has ruled that an application over the long-running so-called "gay cake" case is inadmissible.
The court has said that the decision is final.
In 2018, the UK Supreme Court ruled that Northern Ireland gay rights activist Gareth Lee was not discriminated against when the Christian owners of a Belfast bakery refused to make him a cake iced with the slogan "Support Gay Marriage".
Mr Lee then referred the case to the ECHR, claiming that the Supreme Court failed to give appropriate weight to him under the European Convention of Human Rights.
Mr Lee claimed that his rights were interfered with by the decision of the UK's highest court to dismiss his claim for breach of statutory duty to provide services, and the interference was not proportionate.
However the seven-judge chamber of the ECHR said that in order for a complaint to be admissible, "the Convention arguments must be raised explicitly or in substance before the domestic authorities."
The court said Mr Lee had not invoked his Convention rights at any point in the domestic proceedings.
"By relying solely on domestic law, the applicant had deprived the domestic courts of the opportunity to address any Convention issues raised, instead asking the Court to usurp the role of the domestic courts," the ECHR ruling said.
"Because he had failed to exhaust domestic remedies, the application was inadmissible." '
