When CASA went from having the credit card license to the booklet style (ICAO compliant??) license, my middle name was somehow miss-spelt on the new style license. Their mistake clearly with data entry, but for them to change it back to how I had it originally required providing them with a statutory declaration, plus certified copies of my driver's license, passport and birth certificate. A lot of stuffing around when they could have easily referred to past records of my SPL, PPL, CPL and all the ground theory exams I conducted over the years.
