New Delhi: A court here Monday said judges are not "caged parrots" while rejecting a plea seeking further direction to probe the role of former railway minister Pawan Kumar Bansal in the railway bribery case.

The court was hearing a plea moved by NGO Delhi Pradesh Social Progress Society (DPSPS), seeking further direction to the Central Bureau of Investigation (CBI) to investigate Bansal's role, alleging that the agency had not investigated it "purposely".
