The authorities receive the application file, then issue a confirmation (a temporary resident permit or blue card) that confirms the application has been submitted, provided that all the necessary documentation has been submitted with the application. This confirmation is valid for one year and it constitutes an evidencing document until the resident permit is issued. So you have to proceed to a new passport issuance. Thereafter, make contact with your lawyer in order to inform the competent authority regarding the new data of your passport in relation to the lost one and the issued temporary resident permit.
