Law against no legible, current plan doc

[Gary]

A plan is anended to a cash balance plan a few years ago. All that exists are amendments and resolutions, but no restated document. The current docs are w/r to the prior traditional pension plan. The conclusion is that the plan has been significantly changed with extensive papre trails of changes, but no doc. Is there a law against this, when it is to such a large extent? The amendments and resolutions are barely comprehensible due to how lengthy and confusing they are. Any comments out there?
