The roll out of the new currency notes has attracted litigation with at least two petitions filed at the courts today.
EALA MP Simon Mbugua argues that the new notes bear images of a person in contravention of the constitution.
Activist Okiya Omtata has also challenged the legality of the new generation currencies.
It was during the celebration of the 56th Madaraka day in Narok County that the CBK governor would unveil the new currency notes which will be in Sh50, Sh100, Sh200, Sh500 and Sh1000 denominations.
According to the constitution 2010, article 231(4) the new generation notes and coins may bear images that depict or symbolize Kenya or an aspect of Kenya but should not bear the image of any individual.
The front of the new Sh1000 and Sh500 notes however bear the image of the Kenyatta International Conference Centre (KICC) and a statue of Jomo Kenyatta whose statue is erected outside the KICC.
EALA mp Simon Mbugua has already filed a petition challenging the new legal tender saying it is in violation of the constitution since it bears the image of an individual.
Mbugua also argues that the Kenyan public was not consulted on plans to set withdrawal dates in 4 months.
