Chapter 7: Legal basis for processing – Unlocking the EU General Data Protection Regulation

Under the GDPR, the position on this issue has materially changed (e.g., the GDPR has introduced a new obligation that did not previously exist).

Under the GDPR, the position on this issue has not materially changed (e.g., although the wording may be different in the GDPR, the nature of the relevant obligation is unchanged).

The impact of the GDPR on this issue is likely positive for most organisations (e.g., because the GDPR provides certainty in relation to a previously unclear issue).

The impact of the GDPR on this issue is likely neutral for most organisations (e.g., because the requirements under the GDPR and the Directive are essentially the same).

The impact of the GDPR on this issue is likely negative for most organisations (e.g., because the GDPR introduced a new obligation on organisations).

The impact of the GDPR on this issue is unknown at this stage (e.g., because the impact on organisations is dependent upon secondary guidance that has not yet been written).

legal basis

Under EU data protection law, there must be a legal basis for all processing of personal data (unless an exemption or derogation applies).

Rec.30; Art.7(1)

Personal data could only be processed if at least one legal basis applied.

 Rec.39, 40, 41; Art.6(1)

Personal data may be processed only if, and to the extent that, at least one legal basis applies.

 The obligation on organisations to have a legal basis in respect of each processing activity is essentially unchanged.

Consent

Personal data may be processed on the basis that the data subject has consented to such processing.

Rec.30, 33; Art.7(1)(a)

Processing was permitted if the data subject had consented to the processing.

 Rec.32, 42, 43; Art.6(1)(a)

Processing is permitted if the data subject has consented to the processing.

 "Consent" remains a legal basis for processing personal data. However, under the GDPR, valid consent is significantly harder to obtain (see Chapter 8).

Contractual necessity

Personal data may be processed on the basis that such processing is necessary in order to enter into or perform a contract with the data subject.

Rec.30; Art.7(1)(b)

Processing was permitted if it was necessary for the entry into, or performance of a contract with the data subject or in order to take steps at his or her request prior to the entry into a contract.

 Rec.44; Art.6(1)(b)

Processing is permitted if it is necessary for the entry into, or performance of, a contract with the data subject or in order to take steps at his or her request prior to the entry into a contract.

 "Contractual necessity" remains a legal basis for processing personal data.

Compliance with legal obligations

Personal data may be processed on the basis that the controller has a legal obligation to perform such processing.

Rec.30; Art.7(1)(c)

Processing was permitted if it was necessary for compliance with a legal obligation.

 Rec.45; Art.6(1)(c), 6(3)

Processing is permitted if it is necessary for compliance with a legal obligation under EU law or the laws of a Member State.

 "Compliance with legal obligations" remains a legal basis for processing personal data.

 The fact that this legal basis is explicitly limited to legal obligations arising in the EU may place organisations that are subject to non-EU court orders to disclose data in a difficult position.

Vital interests

Personal data may be processed on the basis that it is necessary to protect the "vital interests" of the data subject (this essentially applies in "life-or-death" scenarios).

Rec.31; Art.7(1)(d)

Processing was permitted if it was necessary in order to protect the vital interests of the data subject.

 Rec.46; Art.6(1)(d)

Processing is permitted if it is necessary in order to protect the vital interests of the data subject or of another natural person.

 Under the GDPR, the "vital interests" processing condition can extend to other individuals (e.g., children of the data subject). This is a helpful clarification.

Public interest

Personal data may be processed on the basis that such processing is necessary for the performance of tasks carried out by a public authority or private organisation acting in the public interest.

Rec.32; Art.7(1)(e)

Processing was permitted if it was necessary for the performance of a task carried out in the public interest or in the exercise of official authority vested in the controller.

 Rec.45; Art.6(1)(e)

Processing is permitted if it is necessary for the performance of a task carried out in the public interest or in the exercise of official authority vested in the controller.

 "Public interest" remains a legal basis for processing personal data. Note also that processing carried out on this basis may be subject to objections from data subjects (see Chapter 9).

Legitimate interests

Personal data may be processed on the basis that the controller has a legitimate interest in processing those data, provided that such legitimate interest is not overridden by the rights or freedoms of the affected data subjects.

Rec.30; Art.7(1)(f)

Processing was permitted if it was necessary for the purposes of legitimate interests pursued by the controller (or by a third party to whom the data are disclosed) except where the controller's interests were overridden by the interests, rights or freedoms of the affected data subjects.

 Rec.47, 48; Art.6(1)(f)

Processing is permitted if it is necessary for the purposes of legitimate interests pursued by the controller (or by a third party), except where the controller's interests are overridden by the interests, fundamental rights or freedoms of the affected data subjects which require protection, particularly where the data subject is a child.

This does not apply to processing carried out by public authorities in the performance of their duties.

 "Legitimate interests" remains a legal basis for processing personal data. Note also that processing carried out on this basis may be subject to objections from data subjects (see Chapter 9).

 Parental permission is required to process the personal data of children (and note that a child is anyone under the age of 16). In some contexts (especially online) proving that parental permission has been obtained may be difficult.

Additional powers for Member States

Member States are permitted to introduce additional legal bases for limited purposes connected with national law or the performance of tasks in the public interest.

N/A

The Directive did not explicitly address this issue.

 Rec.40; Art.6(2)

Member States may introduce additional legal bases in relation to processing carried out for the purposes of complying with legal obligations (see Art.6(1)(c) above) or performing tasks in the public interest (see Art.6(1)(e) above).

 This provision is largely intended to allow Member States to preserve certain legal bases that exist under the national laws of the relevant Member States.

 It is not yet clear how Member States will use this power.

Data relating to criminal offences and civil law enforcement

Personal data relating to criminal offences are subject to additional restrictions (and are commonly treated as being analogous to Sensitive Personal Data) because of the potentially significant impact that the processing of such data can have upon the data subject.

It should be noted that the national criminal laws of Member States are outside the EU's legislative competence, and are not governed by the GDPR.

Art.8(5)

Personal data relating to offences, criminal convictions or security measures could only be processed:

• by an official authority; or
• under specific safeguards provided for by Member State law.

Any complete register of criminal convictions could only be kept under the control of official authority.

Member States could provide that data relating to administrative sanctions or judgments in civil cases are to be processed under the control of an official authority.

 Art.10, 23(1)(j)

Personal data relating to criminal convictions and offences or related security measures may only be processed:

• under the control of an official authority; or
• when permitted under EU or Member State law.

Any comprehensive register of criminal convictions may be kept only under the control of official authority.

Member States may impose restrictions on the processing of personal data for the purposes of enforcing civil law claims.

 The restrictions concerning the processing of personal data relating to criminal offences or convictions, and civil law enforcement matters, have not materially changed.

Processing Sensitive Personal Data

The processing of Sensitive Personal Data is only permitted under certain conditions:

Rec.34; Art.8

The processing of Sensitive Personal Data was prohibited, unless:

 Rec.51-56; Art.9

The processing of Sensitive Personal Data is prohibited, unless:

 The changes introduced by the GDPR are positive for most organisations, because they provide additional grounds on which Sensitive Personal Data may lawfully be processed.

• Art.9(4) Member States may maintain or introduce further conditions, including limitations with regard to genetic data, biometric data or health data.

Processing for new purposes

Notwithstanding the "data minimisation principle" (see Chapter 6) there are some circumstances in which personal data may be processed for new purposes that go beyond the original purpose for which those data were collected.

Art.6(1)(b), 13(1)

Personal data could be processed for new purposes, provided that those new purposes were "not incompatible" with the original purpose. Member State law could permit processing for new purposes (beyond the original purpose) if this was a necessary measure to safeguard special public interests (e.g., national security, defence, public security, etc.).

 Rec.50; Art.6(4)

Where personal data are to be processed for a new purpose, the controller must consider whether the new purpose is "compatible" with the original purpose taking into account the following factors:

• any link between the original purpose and the new purpose;
• the context in which the data have been collected, including the controller's relationship with the data subjects;
• the nature of the personal data, in particular, whether Sensitive Personal Data are affected;
• the possible consequences of the new purpose of processing for data subjects; and
• the existence of appropriate safeguards (e.g., encryption or pseudonymisation).

 The Directive permitted the processing of personal data for new purposes, provided that those new purposes were "not incompatible" with the original purpose. This was a reasonably low bar. However, the GDPR makes it harder for organisations to process personal data for new purposes, because the task of determining which new processing purposes are "compatible", and which are not, is an onerous one.

 The fact the GDPR recognises that pseudonymisation reduces the level of risk involved in processing personal data is a positive development for organisations that routinely process pseudonymised data (e.g., clinical trials companies).

Processing not requiring identification

In some circumstances, controllers have an obligation to retain certain data for the purposes of compliance with applicable law.

N/A

The Directive did not explicitly address this issue.

 Rec.57; Art.11(1)

If the purposes for which the controller is processing the personal data do not require the identification of the data subject, the controller is not required to maintain information identifying the data subject in order to comply with the GDPR.

 The GDPR helpfully clarifies the fact that controllers are not required to retain information that identifies data subjects solely for the purposes of complying with the GDPR.
