A Canberra detective has pleaded not guilty to charges relating to his investigation of two brothers who allegedly spied on female tenants.
Trent Madders, who also previously investigated Brittany Higgins' rape claim, has been suspended from his role as a Detective Leading Senior Constable with the Australian Federal Police.
Madders was not present in the ACT Magistrates Court on Thursday, but his lawyer Tim Sharman entered pleas of not guilty on his behalf.
Last month, Madders was charged with aggravated perjury, destroying or concealing evidence and perverting the course of justice.
It is not related to the investigation into, or aborted criminal trial of, Bruce Lehrmann.
Details about the accusations against Madders have not been aired in open court but the particulars of his charges state the alleged conduct took place between June 2019 and August 2020.
Those particulars allege he "made a false sworn statement in a legal proceeding with the intention of procuring someone else's conviction for, or acquittal of, an offence".
Further, it is said he "concealed evidence with the intention of influencing the outcome of a legal proceeding" and "by his conduct, intentionally perverted the course of justice".
It's understood the allegations relate to Madders' involvement in the cases of identical twins Joshua Rod Tiffen, a former ACT police officer, and Kenan Lee Tiffen.
In 2022, the 46-year-old brothers were found guilty of three counts of capturing visual data in an indecent invasion of privacy relating to covertly fitted hidden cameras.
Those findings are currently the subject of an appeal and the pair have not been convicted of any crimes.
Madders is set to face court again in October.
