KEY POINTS:
What's this all about?
John Dewar has been accused of deliberately suppressing or failing to act on sex complaints against police officers in the 1990s.
Who is involved?
Louise Nicholas is the woman at the centre of alleged rape allegations against Clint Rickards and former-police officers Bob Schollum and Brad Shipton.
John Dewar was the chief inspector of Rotorua CIB in 1993 when Mrs Nicholas' says she bought allegations against assistant commissioner Clint Rickards and three former police officers. He is now self-employed.
Why was the case brought?
The Crown alleges that Mr Dewar suppressed Mrs Nicholas' allegations and tried to pervert the course of justice by giving inadmissible evidence at the trial of another police officer with name suppression.
Mr Dewar said he had asked Mrs Nicholas if the allegations were true and she hadn't answered him. Mr Dewar said he thought Mrs Nicholas had lied under oath and didn't push the case further because she could have been charged with perjury.
How did this happen?
Mr Dewar did not report Mrs Nicholas' allegations to the District Commander at the time because he wanted to protect Mrs Nicholas who he thought was lying. Mrs Nicholas said she had given statements to Mr Dewar two times under oath.
Dewar said he investigated the claim.
