If the McCann's Application which was supposedly lodged last autumn had been accepted it would be recorded within the system viewable by the public. The fact that it is not recorded must in reality mean it has either been withdrawn or was rejected at the very first hurdle.

https://www.echr.coe.int/Documents/Your_Application_ENG.pdfYour application to the ECHR:
Do not call the Court to check whether your application arrived
safely. The Court will contact you if it needs any more information.
The Central Office sorts the mail and sends your application to the
legal division whose job it is to deal with it, that is, the legal division
responsible for the State against which the application is lodged. An
application against Germany, for example, will be sent to the legal
division that deals with German cases, because the people working in
that division speak German and are familiar with the country’s legislation.
Your case will then be given a number and examined by a lawyer. This
does not necessarily mean that the Court has accepted your application;
it just means that it has been registered. If the Court contacts you,
you must reply within the specified time, otherwise your file may
simply be rejected or destroyed
