During the period from the acceptance of the bankruptcy application to the administrator's takeover, the debtor's property is in a frozen state, so the corresponding civil litigation or arbitration involving the debtor must be suspended to prevent the court or arbitration commission from making a judgment first to destroy the integrity of the frozen debtor's property and damage the interests of other creditors. This is the purpose of legislation.

However, as you said, the bankruptcy law does not involve the function of resolving disputes over substantive rights and obligations, and substantive disputes must be resolved in courts or arbitration committees. Therefore, "outside the bankruptcy procedure" means that the dispute over the entity's rights and obligations should resume the previously suspended civil litigation or arbitration after the administrator takes over the debtor's property and get a clear result, and then participate in the bankruptcy distribution procedure.
