The City of Kitchener passed a new statute in its Property Standards By-Law prohibiting the distribution of light that disturbed adjacent inhabitants or trespassed on their property.An order to desist such light distribution was issued to 48965 Ontario Ltd.They disputed the order, claiming that the bylaw was too vague and retrospective.

What do you think?Was it being applied retrospectively?Can such a by-law regulating the distribution of light be clear, or is it necessarily vague?
