    1. In the absence of an adequacy decision pursuant to Article 45(3), or of appropriate safeguards pursuant to Article 46, including binding corporate rules, a transfer or a set of transfers of personal data to a third country or an international organisation shall take place only on one of the following conditions:

      These conditions are individually sufficient and jointly necessary (https://hyp.is/e0RRFJCfEeqwuR_MillmPA/en.wikipedia.org/wiki/Necessity_and_sufficiency).

      Each of the conditions listed is a sufficient (but, by itself, not necessary) condition for legal transfer (T) of personal data to a third country or an international organisation. In other words, if any of those conditions is true, then legal transfer is also true.

      On the other hand, the list of conditions (C; let C be the disjunction of the conditions a-g: a or b or c ...) are jointly necessary for legal transfer (T) to be true. That is:

      • T cannot be true unless C (one of a or b or c ...) is true
      • if C is false (there is not one of a or b or c ... that is true), then T is false
      • T ⇒ C
      • C ⇐ T
    1. It may be the case that several sufficient conditions, when taken together, constitute a single necessary condition (i.e., individually sufficient and jointly necessary)
    2. that a number x {\displaystyle x} is rational (S) is sufficient but not necessary to x {\displaystyle x} being a real number (N) (since there are real numbers that are not rational)
