While he had no issue with the woman saying she had bruising, Mr Fairbrother said there was nothing to say they were as a result of the alleged incident.
He said proposed new medical evidence would indicate it was wrong to intuitively link the bruising to the complainant's allegations.
Mr Fairbrother asked the Court of Appeal to look at the new evidence from a doctor about how bruises develop and age.
The doctor was not in the position to comment on the woman's case as there had been no pictures of the bruises.
She had not gone to police with the complaint until three months after it allegedly happened.
Mr Green was not charged until 15 months later.
The doctor's only comment was that there needed to be an element of caution before any assumptions were made about how bruises were caused.
The Court of Appeal reserved its decision.
