In People of the Philippines v. Donato,[35] this Court explained the doctrine of waiver in this wise:
Waiver is defined as "a voluntary and intentional relinquishment or abandonment of a known existing legal right, advantage, benefit, claim or privilege, which except for such waiver the party would have enjoyed; the voluntary abandonment or surrender, by a capable person, of a right known by him to exist, with the intent that such right shall be surrendered and such person forever deprived of its benefit; or such conduct as warrants an inference of the relinquishment of such right; or the intentional doing of an act inconsistent with claiming it."
As to what rights and privileges may be waived, the authority is settled:
x x x the doctrine of waiver extends to rights and privileges of any character, and, since the word ‘waiver’ covers every conceivable right,it is the general rule that a person may waive any matter which affects his property, and any alienable right or privilege of which he is the owner or which belongs to him or to which he is legally entitled, whether secured by contract, conferred with statute, or guaranteed by constitution, provided such rights and privileges rest in the individual, are intended for his sole benefit, do not infringe on the rights of others, and further provided the waiver of the right or privilege is not forbidden by law, and does not contravene public policy; and the principle is recognized that everyone has a right to waive, and agree to waive, the advantage of a law or rule made solely for the benefit and protection of the individual in his private capacity, if it can be dispensed with and relinquished without infringing on any public right, and without detriment to the community at large. x x x[36](Emphasis supplied and citations omitted)
