Colorado is a one-party consent state, so the bakery has no legal claim; and a competent attorney would tell the owner he has no case.
‘’In Colorado, recording or intercepting a telephone conversation, or any electronic communication, without the consent of at least one party to the conversation is a felony punishable by a fine of between $1,000 and $100,000 and one year to 18 months in jail.’’
