Introduction
The Legitimate Interest Assessment (LIA) is a critical tool for organisations aiming to use the “legitimate interest” basis for data processing under the General Data Protection Regulation (GDPR). This guide explains how organisations can determine when and how to apply legitimate interest lawfully. It also provides a clear framework for conducting an LIA, ensuring data protection compliance and upholding individuals’ privacy rights.
Why a Legitimate Interest Assessment (LIA) Matters
Under GDPR, organisations must have a lawful basis to process any form of personal data. While there are six lawful bases, legitimate interest is one of the most flexible and commonly used. However, legitimate interest requires a robust assessment process to ensure it’s truly justified. Conducting a Legitimate Interest Assessment (LIA) allows organisations to balance their goals with the privacy rights of the data subject, providing transparency and accountability.
Six Lawful Bases for Processing Personal Data
The GDPR specifies six bases for data processing, and every organisation must determine a lawful basis before collecting or processing any personal information. Here’s an overview:
-
Consent: This requires explicit permission from the individual. Consent must be freely given, informed, and specific to a particular purpose, such as sending marketing emails.
-
Contract: This basis applies when data processing is necessary to fulfil a contract with the individual, such as when a utility company requires an address to provide services.
-
Legal Obligation: This is used when an organisation must process data to comply with specific legal requirements, for example, when banks process personal data to prevent financial fraud.
-
Vital Interest: Processing may be necessary to protect the individual’s life or someone else’s, often used in medical or emergency contexts where personal data might need to be accessed quickly.
-
Public Task: Used when processing is necessary to perform a task in the public interest or part of a public authority’s duty, such as local councils handling public records.
-
Legitimate Interest: This allows processing if the individual would reasonably expect their data to be used in a particular way, provided the benefits are clear, and the risks are minimal. Direct marketing is a common example of a legitimate interest, but organisations must justify this basis through an LIA.
Conducting a Legitimate Interest Assessment (LIA): A Three-Step Guide
When relying on legitimate interest as a basis for data processing, the GDPR requires a Legitimate Interest Assessment (LIA). The purpose of the LIA is to ensure that data processing aligns with GDPR principles, balancing the organisation’s interests with the individual’s privacy rights.
The Information Commissioner’s Office (ICO) recommends a three-part test to conduct an LIA, which includes the Purpose, Necessity, and Balancing stages:
1. Purpose Test
- Objective: Define the specific reason for processing the data. For example, if the aim is direct marketing, clarify the benefits for both the organisation and the individual.
- Beneficiaries: Identify who benefits from the processing – the organisation, the individual, or both. Wider public benefits can strengthen the justification.
- Consequence of Non-Processing: Evaluate what might happen if the processing did not occur. For instance, if not processing would result in reduced service quality, this could justify proceeding with the LIA.
- Ethical and Legal Alignment: Confirm that data usage is ethical and in line with both GDPR and broader legal expectations.
2. Necessity Test
- Requirement for Processing: Verify if data processing is essential to achieving the stated purpose. This stage tests whether the processing activity genuinely contributes to the organisation’s goal.
- Alternative Approaches: Explore whether a less intrusive method could achieve the same result. For example, using pseudonymised data instead of identifiable data may still fulfil the purpose while protecting individuals’ privacy.
3. Balancing Test
- Relationship with the Data Subject: Assess the nature of your relationship with the individual. Individuals already interacting with the organisation may have reasonable expectations regarding data use.
- Data Sensitivity: Determine if the data involves any sensitive or confidential information that could impact the individual’s privacy.
- Transparency and Expectation: Consider if individuals would reasonably expect their data to be used this way. If not, further steps may be needed to inform them about this data processing.
- Impact on the Individual: Assess the potential impact on the individual, especially if the processing might be considered intrusive.
- Safeguards and Opt-Out Options: Identify any safeguards to reduce negative impacts, such as data minimisation, pseudonymisation, or offering an opt-out.
ICO Checklist for Conducting a Legitimate Interest Assessment (LIA)
To streamline the LIA process, the ICO offers a helpful checklist, summarised here:
Purpose Test
- Clearly define why the data is being processed.
- Identify who benefits from this processing.
- Outline any public benefits and their significance.
- Consider the impact of non-processing.
- Ensure ethical and lawful data use.
Necessity Test
- Confirm that processing supports the stated purpose.
- Check if the approach is reasonable.
- Evaluate alternative, less intrusive methods.
Balancing Test
- Reflect on the relationship with the individual.
- Assess the sensitivity of the data.
- Determine if people would expect this processing.
- Evaluate potential intrusiveness.
- Mitigate impacts through safeguards.
- Offer an opt-out where feasible.
