I'd be surprised if the LA planning portal allows the functionality of a "no objection" submission. It's either "support" "object" or "neutral" - with supporting text.
It's dodgy to present a PC response if no vote has been conducted (on the agenda, minuted etc.)
It could give rise to questions, possibly compensation claim if the applicant is adversely effected, or criticism if there were a planning appeal or judicial review of the application.
Just really bad practice.
