He was not present at the Waigani Committal Court yesterday and again today when his case returned for mention.
His lawyer Greg Manda briefly told the court he will return in September.
A copy of his affidavit and medical certificate was sent via email and was given to the Committal court by Manda today.
Schram was unable to make it back to PNG also due to his medical condition, the court was told.
The court was also told Schram was unable to obtain the original copy of the PHD certificate and needs to go through Court in Italy to obtain it.
Manda said Diplomatic arrangements are also being made for the documents to be presented at the European consulate in Port Moresby once sorted.
Schram's case was adjourned to Sept 27 by the Committal Court.
The National Court on May 22 granted leave for him to temporarily leave the country and return by or before June 12.
He has since not returned nor sought an extension of his bail variation from the National Court.
Meanwhile his lawyer indicated they intend to file a motion in the Committal Court seeking dismissal of his case.
