99. The Court reiterates that the mutual enjoyment by parent and child of each other’s company constitutes a fundamental element of “family life” within the meaning of Article 8 of the Convention (see, among other authorities, Monory v. Romania and Hungary, no. 71099/01, § 70, 5 April 2005 and Tsikakis v. Germany, no. 1521/06, § 74, 10 February 2011).
100. Furthermore, even though the primary object of Article 8 is to protect the individual against arbitrary action by public authorities, there are, in addition, positive obligations inherent in effective “respect” for family life. In relation to the State’s obligation to implement positive measures, the Court has held that Article 8 includes for parents a right that steps be taken to reunite them with their children and an obligation on the national authorities to facilitate such reunion (see, among other authorities, Ignaccolo-Zenide v. Romania, no. 31679/96, § 94, ECHR 2000-I; Nuutinen v. Finland, no. 32842/96, § 127, ECHR 2000-VIII; and Iglesias Gil and A.U.I. v. Spain, no. 56673/00, § 49, ECHR 2003-V).
101. In cases concerning the enforcement of decisions in the sphere of family law, the Court has repeatedly found that what is decisive is whether the national authorities have taken all necessary steps to facilitate the execution that can reasonably be demanded in the special circumstances of each case (see, mutatis mutandis, Hokkanen v. Finland, 23 September 1994, § 58, Series A no. 299 A; Ignaccolo-Zenide, cited above, § 96; Nuutinen, cited above, § 128; and Sylvester v. Austria, nos. 36812/97 and 40104/98, § 59, 24 April 2003).
102. In this context, the adequacy of a measure is to be judged by the swiftness of its implementation, as the passage of time can have irremediable consequences for relations between the child and the parent who do not cohabit (see Ignaccolo-Zenide, cited above, § 102).
103. Finally, the Court has held that although coercive measures against children are not desirable in this sensitive area, the use of sanctions must not be ruled out in the event of unlawful behaviour by the parent with whom the child lives (see Ignaccolo-Zenide, cited above, § 106; and Eberhard and M. v. Slovenia, no. 8673/05 and 9733/05, § 130, 1 December 2009).
