How should the CBI function?
We deem it proper to emphasize that every officer of the CBI associated with the investigation has to function as a member of a cohesive team which is engaged in the common pursuit of a fair, honest and complete investigation into the crimes alleged. It is needless to further emphasize that the exercise has to be performed objectively and fairly, mindful of the fact that the majesty of law has to be upheld and the rule of law preserved, which does not discriminate between individuals on the basis of their status, position or power. The law treats everyone as equal before it and this has to be kept in view constantly in every State action to avoid violation of the 'right to equality' guaranteed in Article 14 of the Constitution.
