A hearing on a $10 billion lawsuit launched by Mexico against US gun makers for enabling guns trafficking to drug gangs has been canceled, according to Mexico’s foreign ministry on Saturday.

The ministry, which has been seeking a US appeals court to reopen the issue, stated that the hearing, which was scheduled for Monday, was canceled last Thursday.

“The judge assigned to the case, Cindy Jorgenson, issued an order canceling the hearing in which she only stated that she is considering excusing herself from hearing the present litigation,” the ministry claimed.

The judge and US court authorities were unable for comment immediately.

Seven in 10 crime guns recovered and traced in Mexico come from the United States, according to U.S. gun control agency ATF. This level nears 80% across the Caribbean, where many countries have backed the Mexican lawsuit.

The Mexican and U.S. governments have recently agreed to boost controls against arms trafficking through an electronic tracking program for weapons seized from criminal groups, but neither has offered details on the plan.
