A Taiwanese court found against Apple in a case related to its iPhone pricing practices, according to Reuters.

It follows an earlier ruling from the Fair Trade Commission in the market, concerning the fact that the US company required advance approval for pricing plans for its iPhone line (devices from iPhone 4 up to iPhone 5S were cited).

The argument made by the authorities is that when Apple transfers devices to its partners for sale – in this case operators Chunghwa Telecom, Taiwan Mobile and Far EasTone – it loses the right to control sales prices.

The issue is also said to have impacted subsidy levels, pricing differentiation between various models, and advertising content, according to the report.

The device maker will be fined TWD20 million (less than $650,000) related to these activities.

Apple can still appeal the ruling.
