Can one EASA authority not to allow initial skill test with ino-examiner?

[Flion]

I'm a Croatian PPL holder, who has done the SE IR training and will finish a CPL training in 2 days in Hungary and would like to attend a skill test for IR and CPL. The procedure is that I, as a candidate, fill in the appropriate form from the CCAA website and send an application for the approval. Then the CCAA writes an approval (basically an act stating that all required conditions are met for a candidate to a attend the skill test and in the same document the examiner is nominated).

Before completing the training, I phoned the Agency's licensing department to clarify some ambiguity regarding the forms filling. During the phone call a licencing specialist told me: "But you can't have an initial skill test with non-CCAA examiner".

I checked the examiner differences document - Croatia, and it is clearly stated that the candidate can nominate non-CCAA examiner for the ST. Does the Authority have the right to deny the nomination and at which condition?

To be clear I do not have any issues with doing the ST with Croatian examiner it's just that my ATPL theory is about to expire and there's not much time to maneuver - It's a high season and examiners are busy flying, there's a logistics of organizing the Croatian examiner visit to Hungary and associated costs with, then the possibility that he doesn't come due to flight cancelation, weather or the the other reason and so on.

With all that being said, can I protect my rights based on what's stated in Examiner differences document? Is there any other rule I should be familiar with? What are my arguments if I'm challenged to protect my rights once I submit the documents?

Thanks

Here's the Examiner differences excerpt.

Sounds like you have to get the non-CCAA examiner approved first.. then fill out your own paperwork. But eventhough it says it clear as day, they still hold all the cards, so you are completely at their mercy.

I would fire them off an email with the above high
lighted and get it in writing they recognize their differences.
