The Commerce Commission narrowed down its modelling to set the regulated price of Chorus's copper lines without any evidential backing and didn't account for a section of the act designed to minimise the risk to investors in telecommunications services, the High Court heard today.
The regulator erred in law when setting the price Chorus can charge for access to its unbundled bitstream access services in that it didn't have any evidential basis to narrow its inquiry and ignored a section of the legislation aiming to support the government's aims in building a nationwide fibre network, counsel for Chorus, David Goddard QC, told Justice Stephen Kos in the High Court in Wellington.
Goddard said the warning signals should have started sounding when the number of countries the commission was using as a benchmark to set the initial price was whittled down to two nations, Sweden and Denmark. At that stage the commission should have considered section 18 of the act, which was designed to protect innovation and investment in the sector.
"The whole point of section 18 is it tells you how to approach uncertainty, it tells you not to risk innovation and investment," Goddard said.
The regulator didn't have a sound reason for limiting its benchmark price range without taking in other factors, or the legislative requirement to support investment, he said.
