PER CURIAM.

The plaintiff, Apple Salon, appeals from the judgment of the trial court dismissing its appeal from the decision of the defendant commissioner of public health upholding a cease and desist order issued by the defendant department of health and social services of the city of Stamford. On appeal, the plaintiff claims that the court improperly dismissed its appeal by finding that the administrative hearing officer's factual findings were supported by substantial evidence. The defendants argue that, during oral argument before the trial court, the plaintiff waived any claim that the hearing officer's decision was not based on substantial evidence.1 We agree with the defendants and therefore affirm the judgment of the trial court.

"Waiver is the intentional relinquishment or abandonment of a known right or privilege.... As a general rule, both statutory and constitutional rights and privileges may be waived.... Waiver is based upon a species of the principle of estoppel and where applicable it will be enforced as the estoppel would be enforced.... Estoppel has its roots in equity and stems from the voluntary conduct of a party whereby he is absolutely precluded, both at law and in equity, from asserting rights which might perhaps have otherwise existed.... Waiver does not have to be express, but may consist of acts or conduct from which waiver may be implied.... In other words, waiver may be inferred from the circumstances if it is reasonable to do so." (Internal quotation marks omitted.) Wiele v. Board of Assessment Appeals, 119 Conn.App. 544, 549, 988 A.2d 889 (2010). On the basis of our review of the record, including the transcript of the hearing before the court, we conclude that the plaintiff waived any claim that the hearing officer's decision was not based on substantial evidence.2

The judgment is affirmed.
