BERLIN (Reuters) - An Israeli man appealed on Monday against a German court s ruling upholding Kuwait Airways  right to ban him from boarding a flight due to his citizenship, a legal decision that triggered sharp criticism from German officials and Jewish groups. The appeal argues that the ruling accepted a racist Kuwaiti law and allowed the airline to override German laws requiring that airlines transport any passenger with valid travel documents, according to the Lawfare Project, which filed the appeal.  We cannot allow our laws to be subverted by the state-sponsored racism of other nations,  said Nathan Gelbart, the German attorney for the group, which fights anti-Jewish and anti-Israeli discrimination around the world. He said the decision by the Frankfurt district court had allowed  anti-Semitic discrimination to be imported into our country and helped whitewash and sanitize it.  Kuwait Airways has not commented on the decision. German Chancellor Angela Merkel and other top officials have vowed to fight anti-Semitism and xenophobia with the full force of the law in recent weeks after protests that included the burning of Israeli flags.  Merkel s spokesman Steffen Seibert said Germany had a historic responsibility to stand by Israel and Jews everywhere. Anti-Semitism remains a sensitive issue in Germany, one of Israel s closest allies, more than 70 years after the end of the Nazi-era Holocaust, in which six million Jews were killed. The Frankfurt court last month ruled Kuwait Airways had the right to refuse to carry the Israeli man on a flight to Bangkok that began in Frankfurt and included a stopover in Kuwait City since it was abiding by the laws of Kuwait, a country that does not recognize the state of Israel. It said Germany s anti-discrimination law applied only in cases of discrimination on the basis of race, ethnic background or religion, not citizenship. The ruling was sharply criticized by German government officials and the Central Council of Jews in Germany, which said the Kuwaiti law was reminiscent of Nazi policies. Three German state parliaments in Bavaria, Hesse and North Rhine-Westphalia, have passed resolutions condemning the airline for its policy. Acting Transportation Minister Christian Schmidt also raised concerns about the issue in a letter to Kuwaiti officials, saying it was  fundamentally unacceptable to exclude citizens because of their nationality,  according to the Lawfare Project. No comment was immediately available from Schmidt s office. A foreign ministry spokesman said Germany s ambassador to Kuwait had met Kuwaiti officials on Nov. 28 to deliver the letter and discuss the issue. A spate of anti-Semitic acts in Germany in recent weeks, including the burning of Israeli flags, have triggered concern and calls by top officials to put more emphasis on the Holocaust in integration courses for migrants. Rights groups say anti-Semitism and violent acts have increased in recent years amid growing support for far-right political groups and the influx of over a million migrants from Syria and other countries that are at war with Israel.
