Key legal question
Whether the proposed tariff surcharge for related rights had to be included in GT S.
Extracted holding
The tariff as approved was not shown to be unlawful or inappropriate; the surcharge was not required.
Extracted reasoning
Art. 60 URG leaves room for legislative concretization; the statutory 10:3 relation and ceiling are binding, and the evidence did not show that the approved tariff yielded an inappropriate remuneration.
