In Anthony Pools v. Sheehan, Maryland’s court ruled that a homeowner injured by a defective diving board installed as part of a swimming pool construction contract could sue under the implied warranty rules that govern the sale of goods, even though the overall contract was heavy on construction labor. The decision adopted the gravamen test: when the harm traces to a specific product supplied under a mixed goods-and-services contract, the law of goods applies to that product, regardless of whether labor made up the bulk of the deal.
The Accident Behind the Case
A homeowner contracted with Anthony Pools for the design and installation of an in-ground swimming pool. The package included a diving board and stand supplied by the contractor. After the pool was finished and in normal use, the homeowner slipped on the diving board and was seriously injured.
The claim was that the board’s surface was not properly designed to prevent slips and that the board was defective when delivered. Anthony Pools argued that it had been hired to build a pool, not to sell a diving board, and that the strict rules governing the sale of goods should not reach a small component of a large construction service.
Predominant Purpose vs. Gravamen
Courts handling contracts that mix goods and services usually pick one legal framework for the whole deal. The predominant purpose test looks at the main goal of the agreement. If labor is the larger and more important part, the entire contract gets treated as a service, and the buyer loses access to the warranty protections that come with the sale of goods.
That framing tends to hurt buyers of big installations. Digging and construction on a pool project usually cost more than the equipment bolted on at the end, so under a strict predominant purpose reading the whole job looks like a service even when thousands of dollars of manufactured equipment is included.
The gravamen test asks a narrower question: what actually caused the injury? If the harm came from a discrete piece of equipment, the rules governing goods apply to that piece, whatever the rest of the contract looks like. If the harm came from poor workmanship during installation, service law applies. The source of the harm, not the dollar weight of the contract, controls.
The practical stakes are straightforward. Careful installation cannot rescue an inherently dangerous product, and a contractor who chooses to supply a defective item should not escape responsibility for it because the same contract also involved heavy labor.
Why the Warranty Rules Reached the Diving Board
Maryland’s commercial law applies to transactions in goods, defined as things that are movable at the time they are identified to the contract.1Maryland General Assembly. Md. Code, Com. Law § 2-1022Maryland General Assembly. Md. Code, Com. Law § 2-105 A diving board is manufactured and movable before it is attached to the pool, so it qualifies as a good even after installation.
Once goods law applies, so does the implied warranty of merchantability. That warranty requires, among other things, that the product be fit for the ordinary purposes for which such goods are used, be of fair average quality, and conform to any promises made on the label.3Maryland General Assembly. Md. Code, Com. Law § 2-314 A diving board a person cannot safely dive from is not fit for its ordinary purpose.
Maryland also restricts a seller’s ability to write these protections out of a consumer contract. Oral or written language attempting to waive, modify, or exclude the implied warranty in a consumer transaction, or to limit the buyer’s remedies for a breach, is generally unenforceable.4Maryland General Assembly. Md. Code, Com. Law § 2-316.1 A contractor cannot bury a disclaimer in the paperwork and defeat the warranty that way.
What the Court Held
The court applied the goods warranty rules to the diving board and let the homeowner’s claim proceed. The reasoning: even in a contract built around construction, individual products supplied under that contract still have to meet the standard of being fit for their ordinary purpose. A jury could then decide whether the board was in fact defective.
The homeowner was not stripped of consumer product protections simply because the board arrived as part of a larger installation. The ruling drew a line against contractors using the service-heavy shape of a contract to escape responsibility for the equipment they chose to supply.
What the Ruling Means for Buyers of Installed Products
If you hire a contractor for a large home installation, the law does not treat every component as swallowed up by the service. When a specific manufactured item fails and causes injury, the gravamen test lets you reach the warranty protections that come with the sale of goods, even if labor was the larger share of the contract price. That covers items like pumps, heaters, boards, and other discrete equipment a contractor supplies and installs.
The practical takeaway for a buyer is that the source of the harm matters more than the label on the contract. A construction contract with a defective product inside it is still, as to that product, a sale of goods, and the implied warranty of merchantability travels with it.
