Obstructed alternative
The label “Obstructed alternative” describes this recurring design mechanism: a relevant alternative within the current decision is hidden, blocked or made materially harder than the business-favoured action. It is a design and research taxonomy, not a standalone legal conclusion. Depending on the complete journey and likely effect, current EU consumer or sector rules may require separate assessment. No published Digital Fairness Act proposal currently creates a pattern-specific prohibition or duty under this label.

Definition
What is this pattern?
A relevant alternative within the current decision is hidden, blocked or made materially harder than the business-favoured action. The label describes a recurring design mechanism; whether a particular implementation is harmful or unlawful depends on the complete journey, audience, evidence and rules within scope.
How it works
A relevant alternative within the current decision is hidden, blocked or made materially harder than the business-favoured action. A real alternative remains technically present but is buried, de-emphasised or placed behind extra discovery effort compared with the favoured route.
Warning signs
- The options address the same decision.
- The alternative is available in principle but requires additional discovery, interaction or recovery from obstruction.
- The asymmetry is not necessary for security, safety or the user's stated task.
Potential harms
- A viable alternative becomes materially harder to discover than the business-preferred account route.
- The asymmetric path can deter a user from reaching a genuine lower-data choice.

What does this look like?
These fictional examples make the design mechanism easier to recognise. They do not depict a real company and do not establish that an individual interface is unlawful.
Illustrative example 1 · Retail basket
A fictional shop displays account creation as the only button and places guest checkout inside a collapsed paragraph titled “Other information”.
Potential consumer harm: A viable alternative becomes materially harder to discover than the business-preferred account route.
Illustrative example 2 · Cookie preferences
A fictional consent layer accepts optional tracking in one click but requires opening three panels and disabling twelve switches to refuse it.
Potential consumer harm: The asymmetric path can deter a user from reaching a genuine lower-data choice.
Guest checkout hidden behind account copy
A fictional shop displays account creation as the only button and places guest checkout inside a collapsed paragraph titled “Other information”.
Save time with an account. The visible action creates an account; the guest path is buried in unrelated copy.. Selected: Create account. Not selected: Continue as guest
Choose a checkout route. Guest checkout and optional account creation appear together.. Not selected: Continue as guest. Not selected: Create account. Choice consequences, expanded: The consequence of selecting “Continue as guest” is displayed beside the option.
Why the first version can mislead: The route adds avoidable effort between the user’s stated intention and completion. In this retail basket example, the obstacle is: “The visible action creates an account; the guest path is buried in unrelated copy.” Evidence should show whether the alternative remains usable and whether “Continue as guest” reaches the represented state. A viable alternative becomes materially harder to discover than the business-preferred account route.
What a fairer design does: Present guest and account routes together with clear consequences and comparable interaction effort.

Review questions (3)
- How many steps, waits and channel changes separate “Create account” from the completed retail basket outcome?
- Capture every peer option, its default state and visual prominence; do those states support “The options address the same decision”?
- Measure the same task through the clearest available route: does the effort difference persist once “Different actions with genuinely different complexity” is accounted for?
Rejecting optional tracking needs multiple panels
A fictional consent layer accepts optional tracking in one click but requires opening three panels and disabling twelve switches to refuse it.
Your privacy options. Acceptance is immediate; refusal is distributed across three nested screens.. Selected: Accept all. Not selected: Reject optional tracking
Choose optional tracking. Accept all, reject optional and customise are visible at the same level.. Not selected: Reject optional tracking. Not selected: Accept all. Choice consequences, expanded: The consequence of selecting “Reject optional tracking” is displayed beside the option.
Why the first version can mislead: The route adds avoidable effort between the user’s stated intention and completion. In this cookie preferences example, the obstacle is: “Acceptance is immediate; refusal is distributed across three nested screens.” Evidence should show whether the alternative remains usable and whether “Reject optional tracking” reaches the represented state. The asymmetric path can deter a user from reaching a genuine lower-data choice.
What a fairer design does: Offer equally direct accept, reject and customise paths while preserving granular settings for users who want them.

What is a fairer alternative?
Place equivalent alternatives in the same decision context with comparable discoverability and no unnecessary steps.
Legal and information status
Legal position at a glance
A relevant alternative within the current decision is hidden, blocked or made materially harder than the business-favoured action. A real alternative remains technically present but is buried, de-emphasised or placed behind extra discovery effort compared with the favoured route. Risk increases where the mechanism changes a material consumer choice, hides a consequence or makes a genuine alternative harder to use. The taxonomy label remains a review prompt and does not establish an infringement.
Dark-pattern research taxonomy
Editorial analysis
The cited research sources support identification and comparison of this recurring interface mechanism. They do not determine that a particular interface is unlawful.
UCPD Articles 5 to 9, where applicable
Possible risk indicator
Depending on the trader, audience, overall presentation, material information and likely transactional effect, the facts may require a separate assessment under the applicable UCPD provisions.
Evidence layers and open questions
Applicable law, enforcement records, policy preparation, stakeholder input, editorial analysis and unknown future details remain visibly distinct.
Current lawCurrent law
The UX label “Obstructed alternative” is not a standalone EU offence. Depending on the trader, audience, complete presentation, omitted information and likely transactional effect, the observed facts may require a separate assessment under the applicable UCPD provisions or another instrument within scope.
Under considerationUnder consideration
The Commission is preparing a Digital Fairness Act initiative, but the call for evidence does not select a final rule for obstructed alternative or establish that this taxonomy term will appear in a proposal.
Editorial analysisEditorial analysis
The pattern definition, variants and examples on this page use the cited research taxonomy sources to support recognition and comparison. That analytical classification is not a legal conclusion about an individual interface.
UnknownUnknown
No published DFA proposal currently establishes a definition, covered actor, legal threshold, duty, remedy, transition rule or application date for obstructed alternative. Those details remain unknown pending primary legislative text.
Context matters
Context and boundary cases
- The options address the same decision.
- The alternative is available in principle but requires additional discovery, interaction or recovery from obstruction.
- The asymmetry is not necessary for security, safety or the user's stated task.
- Exclude or qualify the label where different actions with genuinely different complexity.
- Exclude or qualify the label where exit from an existing subscription, which is classified as hard to cancel.
- Exclude or qualify the label where alternative unavailable for a disclosed eligibility reason.
When a similar design can serve a legitimate purpose
- A similar design should not be classified this way where different actions with genuinely different complexity.
- A similar design should not be classified this way where exit from an existing subscription, which is classified as hard to cancel.
- A similar design should not be classified this way where alternative unavailable for a disclosed eligibility reason.
