There are no "decisive" reasons. Indeed, refusals are issued at the first problem the moderator sees. They do not look further for more. Anything else would be ineffective moderation, and there would be no added value.
This said, there may be more then one reason for a refusal, and they may be in different domains (quality, IP, ...) and you need to address all of them before resubmitting.
