Legitimate Interests under the GDPR Explained

Preparing for the CIPPE exam means mastering practical scenarios that test your knowledge of data protection law, especially the GDPR. One critical topic is understanding when legitimate interests can lawfully justify processing personal data. This question will help you get comfortable with this common, yet complex, area of data protection compliance.

Below, you’ll find a real CIPPE-style practice question on legitimate interests, followed by a detailed explanation and key takeaways. For a quick summary, check out our video explanation on YouTube.

 

CIPPE Practice Question:

A multinational e-commerce company, SwiftBuy Ltd., processes personal data to recommend products based on users’ browsing history. The company argues that obtaining consent for every recommendation would disrupt user experience and lead to unnecessary consent fatigue. Instead, it relies on its legitimate interest in providing a more personalized shopping experience. Some customers have complained, stating they were not aware their data was being used this way.

Which of the following best determines whether legitimate interests can lawfully justify this processing under the GDPR?

A) SwiftBuy Ltd. must conduct a legitimate interests assessment (LIA) to balance its interests against the rights and freedoms of data subjects.
B) Since SwiftBuy Ltd. processes data for a commercial purpose, consent is always required under the GDPR.
C) The company is automatically compliant because online tracking for personalization is standard industry practice.
D) Legitimate interests can never be used for marketing-related processing of personal data.

Correct Answer Explained:

The correct answer is A. Under Article 6(1)(f) of the GDPR, processing personal data is lawful if it is necessary for the controller’s legitimate interests — provided these interests do not override the rights and freedoms of the data subjects.

SwiftBuy Ltd. must perform a Legitimate Interests Assessment (LIA) before relying on this lawful basis. The LIA is a three-part test:

  1. Purpose Test: Is the interest pursued by the company legitimate and lawful? For SwiftBuy, providing personalized recommendations is a legitimate business interest.

  2. Necessity Test: Is processing the personal data necessary to achieve this purpose? The company must confirm that personalization cannot be done with less intrusive means.

  3. Balancing Test: Do the individual data subjects’ rights and freedoms outweigh the company’s interests? This involves considering how the processing impacts user privacy and expectations.

If SwiftBuy fails the balancing test or does not conduct a proper LIA, it cannot lawfully rely on legitimate interests. Transparency is also essential — customers must be informed clearly in privacy policies about how their data is processed.

GDPR Key Points to Remember:

  • Legitimate interests are a flexible lawful basis under GDPR but require careful assessment.

  • Conducting a Legitimate Interests Assessment (LIA) is mandatory before relying on this basis.

  • The LIA involves testing purpose, necessity, and balancing of interests versus rights.

  • Consent is not always required for commercial processing, but transparency and fairness are critical.

  • Following industry practice alone does not guarantee GDPR compliance.

  • Direct marketing can be done on legitimate interests grounds if individuals’ rights are respected.

Explanation of Incorrect Answers

B) Since SwiftBuy Ltd. processes data for a commercial purpose, consent is always required under the GDPR.

This statement is incorrect because the GDPR does not mandate consent for every type of commercial data processing. While consent is one lawful basis under Article 6 GDPR, it is not the only one. Legitimate interests (Article 6(1)(f)) is a valid lawful basis for processing personal data when the processing is necessary for the controller’s legitimate interests and does not override the rights and freedoms of data subjects.
Consent can sometimes be impractical or lead to “consent fatigue,” especially in large-scale personalized marketing scenarios. However, this does not mean that all commercial processing requires explicit consent. Instead, companies can rely on legitimate interests, provided they properly conduct and document a Legitimate Interests Assessment (LIA).
Thus, the blanket claim that consent is always required for commercial purposes is misleading and incorrect.

C) The company is automatically compliant because online tracking for personalization is standard industry practice.

This option is incorrect because following industry practice or standards does not guarantee GDPR compliance. The GDPR requires organizations to individually assess their processing activities against its legal requirements, including lawfulness, fairness, transparency, data minimization, and purpose limitation.
Even if many companies track user data for personalization, each company must ensure it meets GDPR’s conditions independently. Relying solely on common industry behavior exposes the company to risks of non-compliance, especially since supervisory authorities may interpret practices differently or update guidance over time.
Therefore, the assumption that “everyone does it, so it must be compliant” is a risky and legally unsound position.

D) Legitimate interests can never be used for marketing-related processing of personal data.

This statement is false because the GDPR explicitly allows certain marketing activities to be carried out under legitimate interests, provided the controller meets the necessary tests and respects individuals’ rights.
The European Data Protection Board (EDPB) and many data protection authorities recognize legitimate interests as a lawful basis for direct marketing communications, particularly when the data subjects have a reasonable expectation that their data will be used in this way.
However, controllers must conduct a thorough balancing test to ensure the marketing does not unfairly impact the individual’s privacy and must always provide clear opt-out mechanisms.
Thus, it is incorrect to state that legitimate interests are categorically prohibited for marketing purposes.

General Explanation under the GDPR

Under the GDPR, organizations must identify a lawful basis for processing personal data before they collect, use, or share it. One of the most commonly used bases is legitimate interests (Article 6(1)(f)), which allows processing if it is necessary for the organization’s legitimate goals without overriding the rights and freedoms of individuals. However, this basis requires careful consideration and documentation through a Legitimate Interests Assessment (LIA). The LIA evaluates whether the company’s interests are lawful and necessary, and whether the individuals’ rights are adequately protected. Transparency is key — organizations must clearly inform users how their data is used and offer options to manage their preferences. Businesses that fail to comply risk penalties and loss of trust.

Q&A: Common Questions About Legitimate Interests and GDPR

Q: Can companies use legitimate interests to process data for marketing?
A: Yes, but only if they conduct a thorough Legitimate Interests Assessment and ensure their processing does not unfairly impact data subjects. They must also provide clear ways for users to opt out.

Q: Is consent always required for commercial data processing?
A: No. Consent is one lawful basis, but legitimate interests can be used instead if justified properly. Consent is not always practical or necessary.

Q: Does industry practice guarantee GDPR compliance?
A: No. Compliance depends on meeting GDPR’s specific requirements individually, not on what others in the industry do.

Q: What if customers complain about data use for personalization?
A: Companies should be transparent in privacy notices and provide easy-to-understand options to control data use. Properly conducted LIAs and respecting rights help address these concerns.

How Can Legitimate Interest Assessments Help Businesses Navigate Data Privacy Regulations Effectively?

In data protection and privacy regulations, one concept that often comes into play is “legitimate interest.”

But what exactly does this term entail, and how can businesses leverage it effectively while ensuring compliance with regulations like the GDPR? In this post, we’ll delve into the intricacies of legitimate interest and explore how conducting a thorough assessment can benefit businesses.

What is Legitimate Interest?

Legitimate interest refers to one of the lawful bases for processing personal data under the General Data Protection Regulation (GDPR). It allows businesses to process personal data without explicit consent if they have a legitimate reason (or interest) for doing so, provided that this processing does not unduly infringe upon the rights and freedoms of the individuals involved.

How Can Businesses Assess Legitimate Interest?

Conducting a legitimate interest assessment (LIA) is a crucial step for businesses seeking to rely on this lawful basis for processing personal data. An LIA involves a thorough examination of several factors to determine whether the legitimate interest justifies the processing activities. These factors include:

  1. Identifying the Legitimate Interest:
    Businesses must clearly define the legitimate interest they are pursuing, such as fraud prevention, marketing, or network security.
  2. Assessing Necessity:
    They need to evaluate whether the processing of personal data is necessary to achieve the legitimate interest. This involves considering alternative ways of achieving the same goal without processing personal data.
  3. Balancing Interests:
    Businesses must strike a balance between their legitimate interests and the rights and freedoms of the individuals whose data they are processing. They should consider the potential impact on individuals and implement measures to minimize any negative effects.
  4. Documenting the Assessment:
    It’s essential to document the entire LIA process, including the rationale for relying on legitimate interest, the outcome of the assessment, and any mitigating measures implemented to protect individuals’ rights.

Advantages of Legitimate Interest Assessments

Conducting a legitimate interest assessment offers several advantages for businesses:

  1. Flexibility:
    Legitimate interest provides businesses with flexibility in processing personal data, particularly in situations where obtaining consent may be impractical or unnecessary.
  2. Efficiency:
    By conducting an LIA, businesses can streamline their data processing activities, focusing resources on activities that genuinely serve their legitimate interests.
  3. Transparency and Accountability:
    Undertaking an LIA demonstrates a commitment to transparency and accountability in data processing practices. It shows regulators, customers, and other stakeholders that the business has carefully considered the impact of its data processing activities on individuals’ rights and freedoms.
  4. Compliance:
    Perhaps most importantly, conducting a legitimate interest assessment helps ensure compliance with data protection regulations such as the GDPR. By following a structured assessment process and documenting the results, businesses can mitigate the risk of non-compliance and potential penalties.
  5. Enhanced Trust:
    Ultimately, by demonstrating a commitment to responsible data processing practices and respecting individuals’ rights, businesses can enhance trust with their customers and stakeholders. This trust is invaluable in building long-term relationships and maintaining a positive reputation in an increasingly data-driven world.

In conclusion, understanding legitimate interest and conducting thorough assessments can provide businesses with a solid foundation for processing personal data responsibly and in compliance with data protection regulations. By identifying legitimate interests, assessing necessity, balancing interests, and documenting the process, businesses can leverage legitimate interest effectively while prioritizing transparency, accountability, and the protection of individuals’ rights. Ultimately, this approach not only ensures compliance but also fosters trust and enhances relationships with customers and stakeholders.

So, if your business relies on legitimate interest for processing personal data, consider conducting a comprehensive assessment to reap these benefits and ensure your data processing practices are ethically sound and legally compliant.
