I don't know for certain but they definitely do decide sometimes to extend the validity in these circumstances.Thank you again for the reply. So, exactly what I thought. Another quick answer will be appreciated. Back in June 2012, they allowed for a reassessment of a medical exam only if the officer's decision is pending due to an expired medical exam, does this no longer apply?
