It seems the McCanns filed an "appeal" to prolong the process.
Although it's our opinion that that it will not be admitted, in case it is this could delay matters for another 3 years, if we are interpreting this correctly:

A decision on admissibility comes first, then a possible wait of 3 years if application is admitted.
That would allow for OG to continue so that FOIs can be denied on the basis they could interfere with an ongoing investigation.
