This case was considered a landmark as the primary issue had not been before the courts and, up until now, there had been no judicial guidance on its interpretation surrounding 'closeable openings'.
Adam said the bar owner at the centre of the case was still able to operate.
Bar and restaurant owners were urged to check new Ministry of Health guidelines for non-smoking areas.
Even if their venue had complied in the past, they ran the risk of not meeting new criteria.
Adam said a number of establishments continued to take take shortcuts around the Smoke-free Environments Act.
He said there was "definitely room for improvement" as the Government's 2025 smoke-free target grew closer and public opinion shifted in favour of a complete smoking ban in outdoor dining areas.
