The High Court on Friday dismissed a suit challenging the validity of the new currency.
In a judgement where one judge dissented, the court ruled that the image of the founding President Mzee Jomo Kenyatta was not a portrait.
Justices Kanyi Kimondo and Asenath Ongeri also ruled that there was adequate public participation.
The case was filed by activist Okiya Omtatah and EALA MP Simon Mbugua.
