ZURICH, (Reuters) – The appeal by Swisscom over standards used in expanding fibre optic networks to customers was rejected Tuesday by the Federal Administrative Court.

In a statement the court stated that the case revolved around whether Swisscom could use another standard than what the companies in the telecoms industry had adopted in a roundtable meeting with regulators.

Swisscom was prohibited from expanding its network by the Swiss Competition Commission until it had completed an investigation. Swisscom appealed that decision in January.

It ruled that “Swisscom could not credibly prove to the court there were enough technological or economic reasons to depart from the fibreoptic standard.” This verdict can be appealed to the Swiss supreme Court.
