• Picture of a statue is probably not a portrait
• Countries regularly change their currencies
Yesterday Governor Patrick Njoroge said the Central Bank would vigorously contest legal challenges to block the introduction of new currency notes.
The Constitution does say there should be no portraits on banknotes. The new notes do show a statue of Jomo Kenyatta in front of KICC. A portrait normally means a close-up of someone's face which is not the case here. But it is an arguable point.
The other objections are flimsy. There is no constitutional obligation for the CBK to consult on the design of banknotes — and no one has objected to the design of the new coins.
Many countries declare old currency to be void after a certain date. Various years of dollar bills are no longer accepted by the US Treasury. In 2016 India got rid of 500 and 1,000 rupee notes overnight.
Clearly, some people feel that they will lose out when the old Sh1,000 note ceases to be legal tender on October 1. But they will have had plenty of warning. It is their problem if they have too many Sh1,000 notes to exchange legally before that date.
