Supreme Court allows appeal against regulator's refusal to change tariff despite new tariff taking effect.

The Supreme Court quashed the appellate court's dismissal of the energy company's appeal against the regulator's refusal to adjust gas prices. The company argued that unforeseen cost increases justified a tariff revision, while the regulator maintained no grounds existed under administrative law. The court ruled that although a new tariff cannot be retroactively altered, the regulator's refusal to change the old one remains subject to judicial review to prevent unjust economic consequences.
