Gallo Images/Grant Duncan-Smith SA Express (SAX) was placed under provisional liquidation in April 2020 after its business rescue process failed. On Thursday the return date to determine if the state-owned regional airline has to be placed in liquidation, was again postponed. Two unions want to get the Constitutional Court to prevent the demise of SAX, while a previous preferred bidder has submitted a revised offer. The National Union of Metalworkers of SA (NUMSA) and the SA Cabin Crew Association (SACCA) intend asking the Constitutional Court to compel the National Assembly to debate whether state-owned regional airline SA Express (SAX) should be permitted to go insolvent.
