Questione giuridica chiave
Whether the cantonal court wrongly treated the debt as immediately due and misread the December 12, 2008 letter
Decisione estratta
No manifestly incorrect finding was shown; the letter supported recognition that CHF 14,087,480 was due and the mortgage claim became due under the fiduciary transfer agreement.
Motivazione estratta
The court distinguished the letter from a debt acknowledgment but accepted it as proof of due and payable causal claims, which triggered the abstract mortgage claims under the transfer deed.
