Which Governor-General of India introduced the policy of annexation of princely states on the ground of bad administration?

Lord Dalhousie is well-known for utilizing the 'Doctrine of Lapse' to annex states without natural heirs. However, he also annexed the princely state of Awadh (Oudh) in 1856 explicitly on the grounds of "misgovernment" or bad administration, claiming that the British duty to ensure good governance overrode traditional treaty boundaries.
