A coalition of experts and leaders of pro-family organisations from several European countries supported the petition initiated by the Ordo Iuris Institute against the accession of the European Union to the Istanbul Convention.

Two representatives of the European Commission sent a letter to the Marshals of the Lublin, Łódź, Małopolskie, Podkarpackie and Świętokrzyskie Provinces, in which they claim that the authorities of these regions discriminate against specific social groups by adopting pro-family resolutions

The Istanbul Convention undermines the autonomy and the identity of family and restricts the parents’ right to raise children.

The new European Commission declared ratification of the ideological Istanbul Convention one of its top priorities. The document undermines the identity and autonomy of the family, limits parental rights and requires that the authorities eradicate "traditions and customs" regarding the roles of men and women while promoting "non-stereotyped" gender roles. Once the document is ratified, the UE will extend its powers without any basis in the treaties, being able to interfere with the field of family life.

ILGA Europe, an organisation which includes LGBT activists from many countries, has published a report called “Rainbow Europe,” in which it accuses Poland of violating human rights.

The European Commission intends to adopt an extremely ideological document which will negatively impact the family and social norms under the guise of combating violence. The Istanbul Convention undermines the right of parents to raise their children according to their own beliefs and regards traditional gender roles as a ‘source of violence’. In practice, the implementation of this act by the EU authorities will result in its primacy over national laws, despite the fact that the area it regulates lies outside of EU’s competencies.
