A Calgary pastor and his brother are appealing stiff fines and other sanctions imposed after they were convicted of contempt for violating Alberta's COVID-19 rules.

Pastor Artur Pawlowski and his brother Dawid Pawlowski say sanctions imposed last month by Justice Adam Germain are unreasonable, excessive and violate their Charter rights.

As part of their probation, the two men were ordered to include in any public speeches criticizing COVID-19 measures that their views are contradicted by the majority of scientific opinion.

The brothers earlier filed appeals of their convictions for civil contempt.

Artur Pawlowski was fined $23,000 and Dawid Pawlowski $10,000 plus an additional $20,000 in costs to Alberta Health Services for holding church services that flouted rules on masking and physical distancing.
