## Legislator summary

The dispute centered on whether a contract modification agreement, which altered the payment schedule for services rendered, was supported by valid consideration, given that the services were allegedly already required under the original contract. The court reasoned that because the party receiving the benefit did not receive anything new or different from what was already contractually due, the modification lacked the requisite consideration to be enforceable, thus affirming the original contract terms.

Art. 66 al. 1 LTF; Contract Modification Lacking Consideration: The court reasoned that because the party receiving the benefit did not receive anything new or different from what was already contractually due, the modification lacked the requisite consideration to be enforceable, thus affirming the original contract terms.
