The controversial lawyer representing health workers in a failed challenge to COVID-19 vaccine mandates has been suspended by the Law Society of NSW.

Last week, Nathan Buckley, a founding partner of G&B Lawyers, published a letter from the watchdog telling him he had been prohibited from practising until June next year.  

His firm was behind one of the first legal challenges to the NSW vaccine mandate to make it to court, where he argued the public health order was disproportionate when measured against the alleged dangers of the vaccine and the threat of COVID-19, which he claimed could be treated with ivermectin.

It was thrown out by NSW Supreme Court judge Justice Robert Beech-Jones.
