Mr Wanjigi is accused of illegally importing guns to Kenya.
Judge George Odunga temporarily suspended the summon which required Mr Wanjigi to appear before it in person on Monday, March 5.
"A stay of the criminal proceedings in the Nyeri court or any other concerning the subject matter is hereby granted," said Justice Odunga.
Through lawyers James Orengo, John Khaminwa and Nelson Havi, Mr Wanjigi sued the Inspector-General of Police, the Director of Public Prosecutions and the Attorney-General.
Mr Wanjigi was early Thursday charged in a case in which State is pursuing him for illegal ownership of forearms.
It emerged that Mr Wanjigi was summoned following an application by an officer attached to the Directorate of Criminal Investigations (DCI), Maxwell Otieno, who had been investigating Mr Wanjigi in relation to dealings with illegal firearms.
“This was informed by the fact that the suspect had moved to the High Court and obtained anticipatory bail of Sh50,000 which barred his arrest, trespassing on his private property and residence without court order.
“The Investigating officer made application requiring his attendance in court on February 27, 2018,” Mr Nyamache told the court.
There was heavy contingent of police at Nyeri Law Courts on Thursday morning, before the accused failed to appear in court, but would later be charged in absentia.
His lawyer, Mr Kiogora Mugambi, who appeared before Chief Magistrate Wendy Kagendo on his behalf, said the businessman failed to honour the court summons because they appeared ‘fake’.
