Funny formulations in FIDE rules

Interesting how much leeway FIDEs rules would leave for corrupt tournament organizers. Imagine a case where there are special players (say children of influential people) that should (or should not) obtain the top spots.

From article 13: "The arbiter shall act in the best interest of the competition.".

Not being impartial or being fair.

From prephase about arbiters decision making: the solution to a problem [ should be ] "dictated by fairness, logic and special factors."

Allows almost anything...

From General Rules for tournaments, section 04.2 (Swiss): "It is not allowed to vary the correct pairings so as to maximise a players' opportunities to fulfil title requirements."

So otherwise it is OK...?
