STATE OF MADHYA PRADESH AND ORS. vs ORIENT PAPER MILLS LTD.

The Supreme Court upheld the High Court's decision granting exemption from electricity duty under the Madhya Pradesh Electricity Duty Act, 1949, based on the doctrine of promissory estoppel. The Court found that the respondent acted on the assurance given by the State Government on 1.8.1961, which led to its decision to install a power plant. The Court emphasized that it does not typically interfere with factual findings of the High Court unless exceptional circumstances are presented, which were not found in this case.
