Star Equipment, Ltd. v. State of Iowa, Iowa Department of Transportation, 843 N.W.2d 446

IDOT waived the performance bond for a Targeted Small Business (TSB) general contractor on two public projects.
Universal Concrete, a TSB, hired Star Equipment, Manatt’s, and Short’s Concrete as subcontractors for rest-stop improvements; these subcontractors were unpaid after final project acceptance.
IDOT retained a small amount of money ($3,436.75) from Universal Concrete, which was insufficient to satisfy all subcontractors' claims.
Subcontractors submitted claims against IDOT under Iowa Code chapter 573; IDOT moved to dismiss claims exceeding the retainage, arguing 573.2 only allows retainage-based recovery and that extending beyond it would violate state credit provisions.
The district court dismissed excess claims and later granted summary judgments against Universal Concrete for retainage amounts; the subcontractors appealed and the case was consolidated for review.
The supreme court ultimately held that 573.2, as amended in 1988, permits subcontractors to recover from IDOT the unpaid balances owed by the TSB when retainage is insufficient, and that this does not violate the Iowa Constitution; the case was remanded for proceedings on unpaid amounts, interest, costs, and attorney fees.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Does 573.2 require IDOT to pay beyond retainage when bond waiver applies?	Star, Manatt’s, Short’s argue 573.2 extends remedies to IDOT beyond retainage.	IDOT contends remedies are limited to the retained funds; additional payment would violate sovereign immunity.	573.2 permits recovery from IDOT beyond retainage; IDOT is liable as coprincipal.
Does the 1988 amendment create primary liability rather than mere surrogate remedies?	Amendment provides additional remedies against IDOT.	Remedies should not broaden beyond retainage; no primary liability.	Amendment creates primary liability of IDOT to subcontractors, not merely a surrogate retainage remedy.
Is the interpretation of 573.2 constitutional under Article VII, section 1?	IDOT would violate the credit prohibition if it funds private debts.	Constitution permits state payment in public-benefit scenarios.	Provision constitutional; state pays as coprincipal benefiting the public project.
Does 573.2 constitute a waiver of sovereign immunity?	Statutory language shows express waiver.	No waiver beyond retained funds.	573.2 is an express waiver of sovereign immunity enabling recovery from IDOT.
