“Subject to such specific provisions as are expressly provided for in the Treaty and secondary law, all Union citizens residing on the basis of this Directive in the territory of the host Member State shall enjoy equal treatment with the nationals of that Member State within the scope of the Treaty. The benefit of this right shall be extended to family members who are not nationals of a Member State and who have the right of residence or permanent residence.”
“1. Union citizens and their family members shall have the right of residence provided for in Article 6, as long as they do not become an unreasonable burden on the social assistance system of the host Member State. 2. Union citizens and their family members shall have the right of residence provided for in Articles 7, 12 and 13 as long as they meet the conditions set out therein. In specific cases where there is a reasonable doubt as to whether a Union citizen or his/her family members satisfies the conditions set out in Articles 7, 12 and 13, Member States may verify if these conditions are fulfilled. This verification shall not be carried out systematically. 3. An expulsion measure shall not be the automatic consequence of a Union citizen's or his or her family member's recourse to the social assistance system of the host Member State. 4. By way of derogation from paragraphs 1 and 2 and without prejudice to the provisions of Chapter VI, an expulsion measure may in no case be adopted against Union citizens or their family members if: (a) the Union citizens are workers or self-employed persons, or (b) the Union citizens entered the territory of the host Member State in order to seek employment. In this case, the Union citizens and their family members may not be expelled for as long as the Union citizens can provide evidence that they are continuing to seek employment and that they have a genuine chance of being engaged.” (a) the Union citizens are workers or self-employed persons, or (b) the Union citizens entered the territory of the host Member State in order to seek employment. In this case, the Union citizens and their family members may not be expelled for as long as the Union citizens can provide evidence that they are continuing to seek employment and that they have a genuine chance of being engaged.”
“[85] In this context, the Commission, which has the task of proving the existence of the alleged infringement and of providing the Court with the evidence necessary for it to determine whether the infringement is made out (see, in particular, judgment of23 December 2015 in Commission v Greece, C-180/14, EU:C:2015:840, paragraph 60 and the case-law cited), has not provided evidence or arguments showing that such checking does not satisfy the conditions of proportionality, that it is not appropriate for securing the attainment of the objective of protecting public finances or that it goes beyond what is necessary to attain that objective. [86] It follows from the foregoing that the fact that, under the national legislation at issue in the present action, for the purpose of granting the social benefits at issue the competent United Kingdom authorities are to require that the residence in their territory of nationals of other Member States who claim such benefits must be lawful does not amount to discrimination prohibited under Article 4 of Regulation No 883/2004.”
“[I]t is part of the obligations and duties of a police constable to take all steps which appear to him necessary for keeping the peace, for preventing crime or for protecting property from criminal injury. There is no exhaustive definition of the powers and obligations of the police, but they are at least those, and they would further include the duty to detect crime and to bring an offender to justice.”
