Comprendo que el señor Medina Ortega quisiera referirse de manera exclusiva a los documentos públicos y diferenciarlos de los documentos públicos que ha expedido un profesional especializado, delegado de la autoridad pública, de los que se han certificado mediante una firma privada.
I understand that Mr Medina Ortega would like to refer exclusively to authentic acts and differentiate between authentic public acts issued solely by a specialised professional, delegated by public authority and those certified with a private signature.
