This may be the meaning.

I can't recall now any specific term for "instruído", but what it means, in the context, is that all supportive/required documents have been introduced or annexed to the application by the applicant. It is complete

The application is now apt to be adjudged by the competent authority, as far as the obligation of the applicant goes (i.e. presenting all documents required to go with his application).

In law, "fase de instrução" is equal to the common-law discovery:

'Part of the pre-trial litigation process during which each party requests relevant information and documents from the other side in an attempt to "discover" pertinent facts. Generally discovery devices include depositions, interogatories, requests for admissions, document production requests and requests for inspection.' (The Lectric Law Library)
