The ECHR has ruled that their case was inadmissible. The was the case where the supreme Court ruled Christian bakers should not be forced to say/write something they disagreed with.
My understanding is up to now the case has been based on domestic law which is not the remit of the ECHR. In order to bring a case to them they must pursue a human rights case through the domestic courts first.
