Module 1: Contracts and Transactions in E-Commerce

          The digital age has created numerous new commercial opportunities. Common business transactions can be accomplished with the click of a button, and agreements can be made and carried out entirely online. However, the technological changes that have revolutionized modern commerce also raise novel legal issues, particularly pertaining to the form and enforceability of contracts made and carried out electronically.

 Websites face potential legal liability and other adverse consequences for several common activities in digital commerce. In this first module, we begin with a discussion of contracts of adhesion and their use in web and software-based agreements. Next, the discussion turns to best practices and policy guidelines that regulators have developed for electronic transactions and the model laws created for e-commerce agreements. The analysis then concludes with a discussion of how the law has developed to address contracts made in electronic form, including the validity of digital signatures and electronic records.


Contracts of Adhesion in Digital Commerce


          The internet age has given rise to entirely new forms of contracts, as well as new ways that e-commerce companies and their customers trigger contractual liability. Online companies often manage this liability by publishing documents explaining the terms of the website. It is now a standard practice in e-commerce to require customers to abide by published “terms and conditions of use” or “terms of service” to conduct transactions on a site or sometimes even to browse it. These documents are used to explain what a website may and may not be used for, and customers are permitted to view and use the website upon the condition that they follow the published terms of service.  Websites also commonly publish notices and disclosure documents required by consumer protection regulations.

    This express disclaiming and limiting liability is an important way that e-commerce sites manage risk. However, whether they always stand up to a legal challenge is a different matter. Many of these contracts qualify as “contracts of adhesion,” meaning that the offeree (in this case, the website user) must either agree to or refuse all the offered terms.  These contracts typically offer no bargaining power to the consumer, and as a result, courts tend to view them with increased judicial scrutiny. 

The software industry has shifted the notion of assent in contractual agreements from traditional oral or written formats to more abstract means. In fact, the tech industry gave rise to an entire category of contracts that originated with what is now known as “shrinkwrap” agreements.  Shrinkwrap agreements are made when the offeror – a software company, most often – lists terms of use and other requirements on its packaging, and the offeree manifests his or her assent by opening the plastic wrapping around the package.  These agreements have evolved into several forms, each of which requires a customer to manifest assent by engaging in some intentional conduct.  For example, some websites require visitors to accept their terms and disclosures by clicking “I agree” or a similar prompt that appears on web browsers’ screens. These agreements, deemed “clickwrap contracts,” require website users to consent to the website’s terms by action - the click of a button.  “Scrollwrap agreements” also require web browsers to accept terms and conditions before using a site. However, rather than clicking a button, scrollwrap requires consumers to scroll through the contract before it is deemed accepted.  

    So long as clickwrap agreements provide consumers with sufficient detail of the site’s terms and conditions, acceptance by click is considered valid, and these agreements are typically enforceable.   Likewise, scrollwrap contracts also create legally-binding agreements so long as they are structured in a manner that requires clearly demonstrated assent by action.  Although they qualify as contracts of adhesion, they meet the standards of notice and voluntary acceptance necessary to create binding agreements. 

    Some websites require consumers to agree to terms and conditions simply by accessing the content. Because they do not require the same degree of volitional acceptance as clickwrap and scrollwrap agreements, these so-called “browsewrap agreements” are often invalidated by reviewing courts.  Generally, the standard for enforceability of clickwrap, scrollwrap, and similar agreements is whether the customer had a reasonable opportunity to review the offer and manifest assent by some demonstrable means.  Browsewrap contracts will only hold up if a website user has actual or constructive knowledge of the site’s terms and there is evidence of assent.  If these fundamental elements of notice and volitional acceptance are not shown by the facts, the websites’ terms of use and other representations are unenforceable. 

Best Practices and Policy Guidelines for Electronic Transactions

            The field of e-commerce law is relatively new.[15] However, over time, courts and regulatory agencies have developed recommended best practices and guidelines for e-commerce sites to ensure fair dealing in digital transactions. By following these guidelines, websites can help ensure that both their stakeholders and their customers are properly protected during their electronic dealings.

Even though the Federal Trade Commission rules on mandatory disclosures were first developed to apply to brick-and-mortar establishments, they apply to domestic transactions accomplished electronically as well. In 2000, following a public comment and rule making procedure, the FTC issued its “Dot Com Disclosures” guidance document. This policy statement clarified that the FTC’s rules and regulations promulgated under the Federal Trade Commission Act apply to virtual activities just as they do in the “real world.”[16] 

The FTC requires all legal disclosures made electronically to be clear and conspicuous. This means that online representations must be near the website’s product or service, appear for a sufficient duration or be unavoidable to web viewers, and be presented in a form that the average web consumer would be able to understand.[17] For example, if the terms of use are hyperlinked rather than spelled out on the screen, the link should be clearly visible and properly labeled. Likewise, if web browsers access web content via mobile devices, the disclosures must be presented in a manner that is clear on small screens.[18] The agency places the responsibility on the website owner to ensure that consumers receive proper notice of mandatory disclosures, so e-commerce sites should regularly review consumer behavior to make sure their legal rights are properly protected.[19]

It is the website owner’s responsibility to understand which industry-specific agency rules apply to the online business.[20] It is also the website owner’s responsibility to ensure that the customers are properly informed, so disclosures must be clear. If necessary, information should be repeated to ensure online consumers receive proper notice, and any website offering online purchasing options is responsible for making sure that customers are fully aware of their rights and obligations before they buy.[21] The FTC does not distinguish between representations, warrantees, or advertisements made online or in print, so e-commerce companies must be able to demonstrate that all online claims are truthful, fair, and capable of being substantiated by objective evidence.[22]


Models for e-Commerce Agreements


            To be legally enforceable, electronic agreements must comply with the standards established by legal precedent in the common law and the Uniform Commercial Code. Because digital transactions don’t always fit squarely in the traditional structure under which these rules developed, the National Conference of Commissions on Uniform State Laws has developed a model law designed to integrate digital transactions into the framework established by the UCC.[23] The model law, dubbed the Uniform Computer Information Transactions Act, attempts to harmonize contracts common in cyberspace, such as hyperlinked agreements, affiliate agreements, licenses, mandatory disclosures, terms of use, and online shopping and bidding agreements, into the existing legal infrastructure governing contract law.[24]

            This uniform act was originally drafted in the late-1990s, and it aimed to create a uniform set of standards for information technology transactions that don’t fit squarely within the UCC’s rule regarding the sale of goods. Despite its potential usefulness, however, it was never widely adopted. Critics complained that it was too dense and confusing to be practical and that its limited scope and many loopholes made it possible for software companies to carry out questionable business practices.[25] In response to these concerns, the American Law Institute drafted its own model law, the Principles of the Law of Software Contracts.[26]

            The Principles address four common legal issues in electronic contracting:

-       The identification and nature of digital transactions,

-       Contract formation and industry best practices,

-       The application of federal intellectual property law and electronic contracting, and

-       Specific issues of e-commerce law pertaining to warranties, remedies, and transfer.[27]

Rather than following the codified structure of the UCC and original model statute, the Principles are designed like a Restatement, which is a series of rules written by experts as to what the law is in an area, rather than as a model code.[28] They are meant to provide guidance to courts and lawmakers addressing issues common in electronic transactions, and they have proven to be a useful tool in the review of contracts in e-commerce.

For example, the Principles offer a test for determining whether an e-commerce business is dealing primarily in goods under Article 2 of the UCC or in software contracts that are more properly addressed by federal intellectual property laws. Known as the “predominant purpose test,” it looks at whether the predominant factor, thrust, and purpose of the contract, reasonably stated, is the rendition of a service, with goods only incidentally involved, or is a transaction of sale, with labor incidentally involved. [29]

            In addition to providing an authoritative source on the proper nature and scope of electronic contracts, the Principles address the procedures for the formation of these agreements. The formation rules for electronic agreements and software licenses are broad, allowing for the creation of enforceable agreements by any methods the parties choose.[30] The Principles also allow for so-called “rolling contacts” in which customers agree to different terms at different times.[31]

For example, Hill v. Gateway 2000 involved a customer who purchased a computer over the phone. When the computer arrived, the box included Terms of Service that included a 30-day satisfaction warranty. The plaintiff became unsatisfied after the warranty period had elapsed and sued for the return of his money, arguing that the 30-day warranty should be an unenforceable supplemental term that was added after the contract for sale was formed over the phone. The court disagreed, finding that the parties had a rolling contract to which the customer assented, first over the phone and then again - to the supplemental terms - when he opened the box and kept the product beyond the thirty day period.[32]


Filling Gaps and Interpreting Electronic Agreements


            Like the UCC, the Principles offer helpful “gap-fillers” and “battle of the forms” provisions.[33] They apply the standards for physical records found in UCC § 2-207 (applicable when terms of the acceptance vary from those of the offer) to electronic records, but provide special rules for cases where software or other protected electronic property is transferred to a third party.[34] These clarifications are particularly significant in electronic contracts, as in the past, third-party transferees have argued that they cannot be bound to the terms of service agreed to by the original purchaser.[35]

             Regarding interpretation of electronic agreements, the Principles provide an objective interpretation rule that instructs courts to begin with the language of the agreement. If the agreement does not address the issue under dispute, courts should then consider the parties’ actions during their performance under this contract and/or their prior course of dealing. If the agreement of the parties is still not clear, a court may look to applicable trade practices in the industry.[36] If the parties to a digital contract disagree over the meaning behind specific words or conduct or the agreement is ambiguous regarding a fundamental term, courts can consider evidence of the parties’ subjective knowledge and intent at the time the agreement was made.[37]

            Finally, the Principles clarify the standards of performance for software contracts, including what qualifies as a breach of the agreement and the remedies available in the event of breach. It defines breach as a party failing to perform as promised without legal excuse.[38] This definition is consistent with UCC Article 2 and the common law, but it also includes key clarifications regarding agency and warranty issues that commonly arise in digital transactions.[39] In determining whether a breach is material, thus warranting cancellation of the contract, the Principles outline six factors in determining materiality. Examples include a supplier’s failure to disclose a material defect and the contracts’ failure to perform its essential purpose.[40] Additionally, the rule stipulates that providers of software that provides electronic services cannot program the software to disable itself automatically unless the customer has actual or effective notice of this possibility.[41]


Digital Signatures and Electronic Records


            Modern technology has altered the landscape of traditional contract law, and state and federal lawmakers have responded in turn. Nearly every state has enacted the Uniform Electronic Transactions Act, which sets forth the requirements for validating digital records and signatures on electronic agreements.[42] The Act was drafted in 1999 to remove unnecessary legal barriers to the growing field of e-commerce. It establishes the forms and types of electronic records and signatures that are considered equivalent to signed paper agreements.[43]

            The Electronic Signatures in Global and National Commerce Act (often referred to as “E-Sign”) is the federal counterpart to the Uniform Electronic Transactions Act.[44] This federal law officially legitimizes electronic records and e-signatures and prohibits courts from denying enforcement of a contract solely because the parties executed it electronically.[45] E-Sign also lays out the ground rules for validating the authenticity of electronic signatures and ensuring that digital agreements are not improperly modified.[46] First, E-Sign requires that the customer consent to engage in electronic communications or they must be sent on paper.[47] Further, a customer may demand an electronic record to be produced on paper or by other means and may withdraw his or her consent for electronic communications at any time.[48] Withdrawing consent, of course, does not negate already agreed-to terms, but it does prevent future binding electronic agreements.

            Together, these laws establish the legal legitimacy of electronic signatures, communications, and records in digital transactions. Because most states had already adopted the Uniform Electronic Transactions Act by the time Congress enacted E-Sign, the federal legislature decided to include a provision that, where they conflict, the federal law typically defers to the uniform act’s substantive requirements.[49]



            Over the past decades, e-commerce has developed from an emerging industry to a regular part of our daily lives. Most of us purchase goods and services, post media, perform financial transactions, review proprietary information, and perform other important activities online on a regular basis. Fortunately, as electronic transactions have become more common, the law of digital commerce has developed solutions to some of the new issues raised by the internet age.

Despite the novelty of many electronic transactions, courts and legal scholars have worked out a relatively straightforward standard for review of contracts common in software and information technology transactions. Likewise, state and federal lawmakers have developed statutes setting forth requirements for validity and authenticity of electronic agreements and consumer protection agencies have created guidelines for mandatory disclosures and other best practices for fair dealing. These legal protections create a robust framework that helps to make sure e-commerce customers and businesses are protected in their daily activities.

            In our next module, we will turn to privacy protections that are so important to online activities and transactions.
