The security detail of Chief Justice Martha Koome was allegedly withdrawn and officers attached to the Judiciary Police Unit reduced.
The Judiciary made the claims in a letter addressed to Interior CS Kipchumba Murkomen and Inspector General of Police Douglas Kanja on Thursday.
In the letter seen by the Star, the Judiciary protested the move, terming it one that undermines its independence, threatens institutional integrity, and sets a dangerous precedent that suggests key constitutional offices can be undermined through external pressure or retaliation.
The National Police Service had said the officers have not been withdrawn but have been recalled to attend their promotional courses.
