        (b) the issuer may have violated laws regulating the conduct of his business; or

    (810 ILCS 5/7-402) (from Ch. 26, par. 7-402)
    Sec. 7-402. Duplicate receipt or bill; overissue.
    Neither a duplicate nor any other document of title purporting to cover goods already represented by an outstanding document of the same issuer confers any right in the goods, except as provided in the case of bills in a set, overissue of documents for fungible goods and substitutes for lost, stolen or destroyed documents. But the issuer is liable for damages caused by his overissue or failure to identify a duplicate document as such by conspicuous notation on its face.

    (3) Unless the person claiming is one against whom the document confers no right under Section 7--503(1), he must surrender for cancellation or notation of partial deliveries any outstanding negotiable document covering the goods, and the bailee must cancel the document or conspicuously note the partial delivery thereon or be liable to any person to whom the document is duly negotiated.
    (4) "Person entitled under the document" means holder in the case of a negotiable document, or the person to whom delivery is to be made by the terms of or pursuant to written instructions under a non-negotiable document.

    (810 ILCS 5/7-404) (from Ch. 26, par. 7-404)
    Sec. 7-404. No liability for good faith delivery pursuant to receipt of bill.

This rule applies even though the person from whom he received the goods had no authority to procure the document or to dispose of the goods and even though the person to whom he delivered the goods had no authority to receive them.
