Building Authority Problems - Purchased a Defective Plot

And what good does that do the OP for his problem?

Nothing, just had to get it off my chest. Let's get back to the topic.

not strict at all, you are spreading real nonsense here.

I couldn’t have said it better

An application is not a document,

Yes, even a plan can be a document: a document is any recording of a legal fact, in image as well as text form. Regarding the present application, the authority believes it states that the planned property is cleared – which is not true. Whether the criminally necessary aspect of deception with the intent to gain an advantage is present, the approval authority reasonably does not want to open that can of worms here. The false document in the application is the attached plan representation, which falsely depicts the property as completely cleared. But the authority does allow the possibility to correct this by considering the application as merely incomplete – because with the partial demolition application concerning the remaining remnants (or with the explanation of their integration into the future building ensemble), the consistency between facts and representation would be restored.

No, it does not become true by interpreting lay opinions into it. You can believe me: false information in an application is not forgery. Already contested in court.

Not only laymen's but also lawyers' opinions are not always "valid" -

In case of doubt, Hamm. Hamm has an opinion on everything

Forgery of documents basically only applies if you
a) sign "with a false name"
b) falsify an existing document

Writing something false down and signing it in your own name is not document forgery. You can certainly encounter professional issues or someone might suspect fraud in certain applications - but document forgery is something else.
