The man known as "Nick", whose allegations sparked the VIP sex abuse probe, will stand trial next year charged with lying to police and fraudulently receiving £22,000 in compensation.
The 50-year-old, whose real identity cannot be revealed for legal reasons, is accused of 12 counts of perverting the course of justice and one count of fraud - and appeared at Newcastle Crown Court via videolink.
No pleas were entered, but his barrister Raymond Tully said: "We anticipate that the matter will be fully contested."
Judge Paul Sloan QC, the Recorder of Newcastle, set a trial date for March 5.
Nick's claims about the existence of a VIP Westminster paedophile ring led to Operation Midland, which saw the homes of figures including Lord Bramall and Lord Brittan raided.
However, the £2.5m Metropolitan Police investigation closed having found no evidence of any wrongdoing.
In September 2017, Northumbria Police passed a file to the Crown Prosecution Service which led to Nick being charged.
