It means that the examination of your case is finished, and thus it will not be subjected to evidentiary proceedings with regard meeting the requirements for granting a residence permit. Your case can be discontinued at your request (for instance, when you would want to leave the territory of Poland, and you do not want the residence permit to be granted) or ex officio (when certain permanent and irremovable obstacles have appeared rendering the further processing of your case impossible). If you are not satisfied with the decision, you may file an appeal.
