I need help understanding a court cases DECISION and COURT REASONING. The court case is: MKL Prepress 840 NE 2d 687. From the case it is stated "Had plaintiff exercised due diligence in this instance, Landwer or another individual with the authority to do so would have held defendant's check or returned it with an explicit rejection of defendant's tender offer. It is apparent from the record that such was not the case, and we cannot conclude that the circuit court was in error in finding for defendant.

For the reasons set forth above, we affirm the judgment of the circuit court.

Affirmed."

I just asked a question on this to you'll and I was told " The Appellate Court overruled the lower courts decision." it is clear from the case they affirmed it. Please help me, I am very confused and it is due tomorrow. In the decision say what was decided in the lower court and also in the Appellate Court. Thank you
