Questão jurídica principal
Whether the appellants sufficiently substantiated their objection to the supplemental offer dated 16 May 2002, especially the price increases and surcharges.
Decisão extraída
The lower court had not properly addressed the appellants' objections to the amount of the claimed work price; the matter had to be reassessed on remand.
Fundamentação extraída
The appellants had challenged not only the necessity of the works but also the amounts and surcharges. The contractor bore the burden of proving the amount of the work price. Because the appellate reasoning was incomplete and unclear, meaningful review was impossible.
