Insolvent Mexican supermarket operator Comercial Mexicana, which recently received notice that its second petition for bankruptcy protection in Mexico had been rejected by a Mexican court, will probably present a third petition, according to a Sentido Comun.com report.  It continues to negotiate its approximately US$2 billion of debt with creditors.  Fortunately for La Comer, there is no three strikes and your out rule in Mexican bankruptcy petition filing.
