The billionaires that made their fortune off opioids are asking a federal court to grant sweeping legal immunity to their family and to more than a thousand parties linked to the family and the scandal, including one of their companies peddling opioids across the globe, according to new court records reviewed by the Daily Poster.

If the court blesses the requested releases — and if Congress does not quickly pass pending legislation to halt such immunity — government officials would be prevented from bringing opioid-related lawsuits against not only Sackler family members and their businesses, but also against the Sacklers’ army of lawyers, family trusts, foundations, investors, film companies, and even other pharmaceutical companies that manufacture and sell opioids.

The immunity request was filed by lawyers for Purdue Pharma on Wednesday as part of a larger disclosure in the opioid giant’s ongoing bankruptcy proceedings. Members of the Sackler family are seeking the liability shields in exchange for contributing more than $4 billion to a bankruptcy settlement. Their company, Purdue, represented a 16 percent share of the opioid market according to ProPublica and Stat News — and a federal study released last month found that the public health cost of the opioid epidemic was $1 trillion in 2017 alone.
