If the case concluded and a guilty verdict found, that would absolutely be the case.The conduct of some very senior people needs external and impartial scrutiny and if necessary some recommendations as to their ongoing fitness for roles in public life at the very minimum
However, now with the case withdrawn, there is every chance those 'very senior people' were acting in the best interests of everyone involved, including the public interest.
Or are you referring to a Royal Commission that is broader than this specific case?
