So, are you suggesting FINRA will remove the BioAmber ticker symbol at the behest of a US Court or a Canadian Court?
If shares are cancelled, they will not only be cancelled in the "good old USA", they will also be cancelled in Canada, India, Madagascar, and basically anywhere and everywhere a shareholder might exist. For example, if there are investors in outer space, shares will also be cancelled on Uranus.
Still, for those who are easily influenced by repetitive language, FINRA must receive notification in order to "cancel" shares. Insofar as some would like you to believe, the impetus to cancel shares does not arise within FINRA. They execute the order upon notification after shares have already been cancelled via the courts.
