Poland wants the European Commission to drop its case against Warsaw, which Brussels has accused of illegally reneging on a commitment to take in migrants.
Last month, the commission decided to launch procedures against Poland, the Czech Republic and Hungary for failing to take in migrants from camps in southern Europe, which Brussels said was against EU laws.
The countries were given a month to respond.
Poland's interior ministry has said there are "systemic deficiencies in the ... relocation mechanism, which makes it impossible to guarantee security".
