In Chile, the Second Environmental Court ruled in favor of Interchile S.A. regarding a dispute over its Compliance Program (PdC). The ruling addressed the rejection of the program by the Superintendency of the Environment (SMA) concerning infractions related to the ‘Plan de Expansión Chile LT 2×500 kV Cardones-Polpaico’ project.

The court found that the SMA violated the duty to motivate administrative acts and the principles of conclusiveness and contradictoriness. It determined the administration failed to address the full range of charges and allegations presented by the company, noting that the SMA limited its response to only specific charges. The court emphasized that the administration is obligated to resolve all allegations made by interested parties so that companies can understand the specific deficiencies attributed to them.
