Key legal question
Whether the opposition against the 21 November 2007 decision was time-barred and whether the deadline should be restored.
Extracted holding
The claimant did not seriously challenge the finding that his opposition was late and failed to establish a valid reason for restoring the opposition period.
Extracted reasoning
He merely repeated health-related arguments and relied on facts irrelevant to the timeliness issue; this did not undermine the cantonal court's conclusions.
