Key legal question
Whether the cantonal court acted arbitrarily in relying on the TCS speedometer test to assess the speeding offence.
Extracted holding
No. The lower court could reasonably rely on the technical test, which showed the actual speed was always higher than the dashboard indication and sufficiently supported the finding of speeding.
Extracted reasoning
Arbitrariness requires a manifestly untenable assessment, not merely an alternative plausible view. The TCS test, produced by the appellant, showed a systematic underreading of the speedometer and supported the conclusion that the driver should have noticed exceeding the limit.
