Conn. Gen. Stat. § 42a-5-109

(b) If an applicant claims that a required document is forged or materially fraudulent or that honor of the presentation would facilitate a material fraud by the beneficiary on the issuer or applicant, a court of competent jurisdiction may temporarily or permanently enjoin the issuer from honoring a presentation or grant similar relief against the issuer or other persons only if the court finds that: (1) The relief is not prohibited under the law applicable to an accepted draft or deferred obligation incurred by the issuer; (2) a beneficiary, issuer or nominated person who may be adversely affected is adequately protected against loss that it may suffer because the relief is granted; (3) all of the conditions to entitle a person to the relief under the law of this state have been met; and (4) on the basis of the information submitted to the court, the applicant is more likely than not to succeed under its claim of forgery or material fraud and the person demanding honor does not qualify for protection under subdivision (1) of subsection (a) of this section.

See Sec. 42a-5-108 for successor provisions to Sec. 42a-5-109, revised to 1995, re issuer's obligation to its customer.
