The law surrounding Chapter 11 reorganisation plans only covers the relationships and responsibilities between debtors and creditors. It doesn't say anything about third parties.

But it does include a term saying a plan "may" also "include any other appropriate provision not inconsistent with the applicable provisions of this title" - subject to the approval of a judge.

Applying the broadest possible interpretation of this catch-all wording would produce absurd results - a bankruptcy plan would be more powerful than the constitution itself. So courts have to figure out just how broad an interpretation to apply.
