I think lawyers fundamentally premise their work on the variability of interpretation. They make arguments in favor of certain interpretations, and take pains in the texts they write to preempt any undesirable interpretations. Legislators may or may not think like writers/lawyers, but even if they do they're constrained by those who don't, the need for compromise, and the incentive to have gotten something done even if it's not perfect. So they sometimes end up doing a bad job of legal writing.
