It was “must”. It would be two years for the individuals who would have gone.
You are correct that there was a monthly communication report last February for a meeting that would have occurred in January with one of the members of Parliament who accepted a trip. CIJA advised me in February that they realized this individual had been invited to a presentation by CIJA by mistake. They were forthright in letting me know that they had made a mistake and would not do that again. It was an oversight that the MP had been invited and I accepted that explanation.
