Is there any way to have access to PG&E cases in the recent bankruptcy court? Are they public?
While PACER needs a case number, I could find the case number via Google by googling
PG&E Bankruptcy PACER, resulting in the result of the US Bankruptcy Court, Northern District of California, telling the case number is 19-30088-DM, jointly administered with 1930089-DM under the Honorable Dennis Montali.
Next stage would be to go to PACER, where you'll need to log in and then enter the case number. Note that PACER does bill you by the documents accessed.
As an alternative source, the docket of close to 12 000 filings (in Feb 2022) can be found on the website of Kroll, who handle this bankruptcy case.
