A New York bankruptcy judge ruled Tuesday that subpoenas for financial information involving the Sackler family, which owns the pharmaceutical company Purdue Pharma, can move forward as the company continues to make its way through the bankruptcy process.

Purdue Pharma filed for Chapter 11 bankruptcy in September amid a flood of lawsuits related to the opioid crisis; the company makes the widely used drug OxyContin, which is one of the main substances blamed for opioid addiction.
