Is the contract signed between the industry Committee and the property company valid?

Although the industry committee is the signatory of the property management contract, it signed the property contract with the property service enterprise after the resolution of the owners' meeting and accepted the entrustment of the owners' meeting.

Property service contracts that have not been resolved by the owners' congress are invalid. Similarly, without the authorization of the owners' meeting, the industry Committee has no right to sign property contracts without authorization.
