As noted by Malayan Insurance, respondents had all the opportunity, but failed to object to the presentation of its evidence. Thus, and as We have mentioned earlier, respondents are deemed to have waived their right to make an objection. As this Court held in Asian Construction and Development Corporation v. COMFAC Corporation:
The rule is that failure to object to the offered evidence renders it admissible, and the court cannot, on its own, disregard such evidence. We note that ASIAKONSTRUCT’s counsel of record before the trial court, Atty. Bernard Dy, who actively participated in the initial stages of the case stopped attending the hearings when COMFAC was about to end its presentation. Thus, ASIAKONSTRUCT could not object to COMFAC’s offer of evidence nor present evidence in its defense; ASIAKONSTRUCT was deemed by the trial court to have waived its chance to do so.
Note also that when a party desires the court to reject the evidence offered, it must so state in the form of a timely objection and it cannot raise the objection to the evidence for the first time on appeal. Because of a party’s failure to timely object, the evidence becomes part of the evidence in the case. Thereafter, all the parties are considered bound by any outcome arising from the offer of evidence properly presented.[32] (Emphasis supplied.)
