A veteran post office clerk has been dismissed on grounds of being convicted 27 years ago for clashing with police during an anti-Vietnam war demonstration... the 52-year-old man was stripped of his right to receive a pension although he had paid the premium ever since he joined... No severance pay was granted..
..he was dismissed because they could not employ a person who had been handed a prison sentence under the National Public Service Law.
Rules are rules, even after 27 years.

Think "Goingu Posutoru" will become a common term in the Japanese lexicon?
