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
