Over the last two decades, consumer relations have undergone a profound transformation. A consumer who, at the beginning of the century, went to a physical store, chose a product, entered into a contract, and made a payment, faces a substantially different reality today. 

The exponential growth of the internet over recent years has led several companies to alter how they conduct their business activities. Businesses have progressively adopted new technologies and distribution channels, changing the way they operate and interact with consumers. 

Although this new business model brings several benefits to the consumer, it also raises various consumer law concerns, given that consumers were previously at a disadvantage compared to the other party. 

In remote contracting, consumers may lack direct physical contact with the product, relying solely on information and images provided by the trader. In this context, the right of withdrawal assumes particular importance as a mechanism allowing consumers to reconsider their decision. 

The right of withdrawal is one of the main guarantees attached to distance contracts and off-premises contracts. Its rationale lies in the need to compensate for certain inherent limitations of these forms of contracting, ensuring consumers have a period during which they can withdraw from the contract without giving any reason, as provided by law. 

Decree-Law No. 24/2014, of February 14, establishes the legal framework applicable to distance contracts and off-premises contracts. This decree-law was amended by Decree-Law No. 78/2018, of October 15. 

In distance or off-premises contracts, consumers enjoy the right of withdrawal, which is provided for under Article 10 et seq. of Decree-Law No. 24/2014, of February 14. 

Article 10 (1) states that consumers have the right to resolve the contract without incurring any costs and without the need to state a reason within 14 days. If the service provider or supplier fails to comply with the pre-contractual information requirements set out in Article 4 (1) (l), the withdrawal period is extended by 12 months from the end of the initial period (Article 10 (2)). The parties may agree on a longer period to exercise this right (Article 10 (4)). 

This constitutes a unilateral termination of the contract: one of the parties has the option to revoke their intent to acquire the good or service by withdrawing their consent, thereby setting aside the principle of pacta sunt servanda. 

Consumers must be informed in a clear and understandable manner about the existence of this right, the applicable deadline, and the procedure for exercising it. 

The digitalization of consumer relations has made this issue even more relevant. If entering into a contract can happen in just a few seconds via a computer or smartphone, exercising consumer rights should also be accessible and straightforward. Complex procedures, difficulties in returning goods, or obstacles to receiving refunds can compromise the practical effectiveness of a right that is formally guaranteed. 

However, the right of withdrawal is not absolute. The law foresees several exceptions justified by the nature of certain goods or services, particularly in situations involving personalized items, sealed goods unsuitable for return due to health or hygiene reasons, and certain digital content. 

The developments of the past 20 years demonstrate that the right of withdrawal has become a cornerstone in adapting Consumer Law to the digital age. The future challenge will be to ensure that this right does not remain merely a formal protection, but functions as a genuinely accessible mechanism for the consumer. 

In an increasingly digitalized, automated market characterized by fast-paced purchasing decisions, the real issue will be ensuring that consumers retain not only the right to contract, but also a genuine opportunity to reconsider their decisions.
