Kernrechtsfrage
Whether the parties concluded a contract for carpet installation on 22 November 2002 despite later disagreement over the completion deadline.
Extrahierter Entscheid
No contract was formed because the defendant's insistence on a strict 15 January 2003 completion deadline was a subjectively essential term that was not accepted.
Extrahierte Begründung
The price and work were agreed, but the later fax showed that the deadline was, recognizably for both sides, essential. The response did not match the offer on all essential points and was therefore a counter-offer, not an acceptance.
