The Motto of CBI
“Industry, Impartiality and Integrity”—the guiding principles set by D. P. Kohli
Industry
The motto begins with “Industry,” capturing the value of hard work, commitment and persistence. D. P. Kohli believed that relentless effort and meticulous investigation were essential for delivering justice.
Impartiality
“Impartiality” emphasizes fairness and neutrality in investigations. Kohli insisted that CBI officers must remain free from influence—political, personal or institutional—to maintain the agency’s credibility.
Integrity
“Integrity” forms the core of the motto. To him, moral strength, honesty and ethical conduct were non-negotiable qualities for every investigating officer. This value continues to define CBI’s identity.
