Apart from the identified exemptions in law (criminality and security), this is contrary to the law. If you think it's happening and have an example, complain to the information access commissioner or ombudsman.Having that said, irrc won’t be releasing all info during an application process as far as GCMS notes are concerned. This is because they don’t want anyone to take advantage of the information and have an edge, info is being censored.All info will be released once the application process is complete and finalized.
If you don't know and are just making this up, well, 'nuff said.
