Pell has always assured law enforcement and Royal Commission authorities in Australia that he will continue to cooperate in every way and that he would even return to Australia to answer summonses. He has appeared via video link with the Royal Commission into child abuse but has declined on medical advice to return home via air transportation.
Cardinal Pell needs to be apprised of the possibility of travelling by air in short sectors like the Rome to London return he completed recently. Then, of course, there is very comfortable, leisurely option of sea travel. One of the challenges Pell is facing however, is that while the Victoria Police probably will decline to press historic child abuse charges against him, the Royal Commission has twice advised him that, in one particular case, it finds his evidence 'implausible.' That is legalese for something else!
