Activist Okiya Omtatah has requested the High Court to compel the Judicial Service Commission (JSC) to take control of all tribunals.
In his application, Mr Omtatah states that currently, there are several tribunals running differently, and that most of them have members who are predominantly appointed by the executive.
"This matter is filed in the public interest to ensure access to justice for users of the tribunal system in Kenya," Mr Omtatah said.
According to him the Executive continues to treat tribunals as its integral part and thus undermining the independence of the Judiciary.
In the Constitution, tribunals are treated as subordinate courts.
The activist claims there is no equal justice before tribunals as some operate as part of government ministries, departments and agencies and others conduct their businesses as independent quasi-judicial bodies.
Hence Mr Omtatah, wants JSC compelled to reconstitute all tribunals.
He has also sued the Attorney-General Kihara Kariuki in a petition filed in Nairobi while Katiba institute is listed as an interested party.
