justice. These standards will, of course, be informed by the common
law principles developed over decades…
197. The High Court in Republic v Fazul Mahamed & 3 Others exparte Okiya Omtatah Okoiti [2018] eKLR added its voice on the
issue, and, as follows: 25.
In John Wachiuri T/A Githakwa Graceland & Wandumbi
Bar & 50 Others vs The County Government of Nyeri &
Ano[39] the Court emphasized that there are three
categories of public law wrongs which are commonly
used in cases of this nature.
These are: a.
b.
c.
Illegality - Decision makers must understand the
law that regulates them. If they fail to follow the
law properly, their decision, action or failure to act
will be "illegal". Thus, an action or decision may be
illegal on the basis that the public body has no
power to take that action or decision, or has acted
beyond it powers.
Fairness - Fairness demands that a public body
should never act so unfairly that it amounts to
abuse of power. This means that if there are
express procedures laid down by legislation that it
must follow in order to reach a decision, it must
follow them and it must not be in breach of the
rules of natural justice. The body must act
impartially, there must be fair hearing before a
decision is reached.
Irrationality and proportionality - The Courts
must intervene to quash a decision if they consider
it to be demonstrably unreasonable as to
constitute 'irrationality" or 'perversity' on the part
of the decision maker. The benchmark decision on
this principle of judicial review was made as long
ago as 1948 in the celebrated decision of Lord
Green in Associated Provincial Picture Houses
Ltd vs Wednesbury Corporation: If decision on a competent matter is so
unreasonable that no reasonable authority
could ever have come to it, then the Courts
can interfere...but to prove a case of that
kind
would
require
something
overwhelming...
