On 23 May conscientious objector Georgios Koutsomanolakis was sentenced to a suspended 24-month prison term for insubordination by the Military Court of Athens. Koutsomanolakis was charged with insubordination in 1979, at a time when there was no alternative civilian service in Greece, because as a Jehovah’s Witness he refused to serve military service on religious grounds. He fled Greece and was granted political asylum in Germany, where he has been living since then. He was arrested and detained on 12 May 2005 on the Greek island of Rhodes during a visit to his parents and on 16 May he was transferred to Korydallos prison, Athens, where he remained imprisoned until his trial.
I promise to try to track down the website source for the above when I have time.
Could the above happen in the USA? In other words, if a law in the USA is revised to conform with international treaties, then can someone who was convicted under the old law be imprisoned even though the new law doesn't criminalize the conduct that violated the old law?
