Key legal question
Whether the Obergericht acted arbitrarily by refusing a further extension of the filing deadline and disregarding the late submission.
Extracted holding
No; the court did not depart from its practice without reason, and the appellant did not show changed circumstances justifying another extension.
Extracted reasoning
The final extension had been expressly marked as final and subject to late-filing consequences. Even without an explicit reference to the statutory emergency period, the appellant could recognize that no further judicial extension would be granted. He failed to substantiate changed circumstances in the last extension request.
