Karygiannis returned to City Hall and resumed his work as a councillor the next day. On December 2, 2019, Toronto resident Adam Chaleff filed an appeal of the decision. On June 24, 2020, the Court of Appeal overturned the Superior Court's ruling stating that Karygiannis had "not clearly demonstrated to this court that this was a mere 'clerical error'" and he was removed from office for a second time. On February 22, 2011, Jim Karygiannis joined a protest rally of the Armenian Youth Federation by the Embassy of Azerbaijan in Ottawa timed to the anniversary of the Nagorno-Karabakh separatist movement in Azerbaijan. During his four-minute speech, he called for the Azerbaijani ambassador Farid Shafiyev to be stripped of his diplomatic privileges and leave Canada. Shafiyev reacted by saying Karygiannis had "crossed the line of civility and decency and used the language of the level of street hooliganism." Later another Liberal multiculturalism critic Rob Oliphant in a telephone call to Shafiyev expressed his regret about his colleague's statement and added that Karygiannis's words did not represent the attitudes of the Liberal Party. In August 2011, Citizenship and Immigration Committee officers complained of Jim Karygiannis using abusive language and an aggressive tone while speaking to them. Karygiannis stated that the accusations were false and part of a "smear campaign against him." As a multiculturalism critic, Karygiannis attempted to unite 19 cultural groups in Ottawa on August 27, 2011, to discuss issues they faced. The event was boycotted by the Jewish, Chinese, Turkish, and Macedonian communities. A spokesperson for B'nai Brith Canada said the Liberal Party should consider putting forth a better representative of the party to deal with multiculturalism matters, due to Karygiannis's being "divisive on some issues", instead of bringing communities together. The Council of Turkish Canadians released a statement where it explained its unwillingness to participate in the event by Karygiannis's "past attempts to promote ethnic division and intolerance against Canadians of different national origin", particularly Turks, Azeris and Macedonians. In mid-August 2011, Karygiannis's former Conservative opponent Harry Tsai, among others, signed a collective letter on behalf of the Taiwanese Canadian Association of Toronto, requesting that Bob Rae remove Karygiannis from his multicultural critic's post. The letter cited his poor attendance of the House of Commons and bad treatment of Canada's Turkish and Macedonian community as reasons to be considered unfit.
