CJEU, Tietosuojavaltuutettu v Jehovan todistajat, C-25/17 (2018):
The existence of joint responsibility does not necessarily imply equal responsibility of the various operators involved in the processing of personal data. On the contrary, those operators may be involved at different stages of that processing of personal data and to different degrees, so that the level of responsibility of each of them must be assessed with regard to all the relevant circumstances of the particular case. Actual access to personal data is not a prerequisite for joint responsibility (p. 68-72).
