Article 12 CRPD: legal capacity and supported decision-making

Article 12 of the CRPD says that persons with disabilities enjoy legal capacity on an equal basis with others in all aspects of life, and that states must provide access to the support they may require to exercise it. It is four paragraphs long and it is the most disruptive provision in the treaty.

The distinction the article turns on

Two concepts are routinely merged and the article depends on separating them.

Mental capacity is a factual claim about a person’s decision-making skills at a given moment. It varies with the decision, the day, the information given and the support available.

Legal capacity is the recognition that a person is a holder of rights and can act on them: sign a contract, open an account, marry, consent to treatment, vote, go to court.

Almost every European legal system has historically used an assessment of mental capacity to remove legal capacity. Article 12 says that is not permitted. Deficits in decision-making skills are met with support, not with removal of status.

What the Committee said

General Comment No. 1, adopted in 2014, is unambiguous. Substitute decision-making regimes, where a guardian decides on the person’s behalf on the basis of what is judged to be in their best interests, must be abolished and replaced by supported decision-making, which is oriented to the person’s will and preferences.

Three features define a substitute regime, and any one of them is enough: legal capacity is removed even for a single decision; the decision-maker is appointed by someone other than the person; and the decision is made according to the decision-maker’s judgement of best interests rather than the person’s own will and preferences.

This reading is genuinely contested. Several state parties, including a number of EU members, have entered declarations or interpretative statements maintaining that substitute decision-making remains permissible as a last resort in narrow circumstances. National courts have divided. What is not seriously disputed is the direction of travel: plenary guardianship, in which a person loses legal capacity across the board, is regarded across European bodies as indefensible.

What supported decision-making actually looks like

The phrase covers a spectrum rather than a single mechanism.

Support agreements, in which a person nominates one or more supporters who help them understand information, weigh options and communicate a decision. The person decides; the supporter’s role is defined by the person and can be withdrawn.

Representation agreements and advance planning, made while a person has clear capacity, setting out what should happen and who should assist if communication becomes harder later.

Communication support, which is often the entire substance of the case. Where a person uses augmentative and alternative communication, the question of whether they can express a preference is frequently a question of whether anyone has provided the means and the time.

Accessible information. A decision cannot be supported if the material is unreadable. This is the direct link to easy-to-read provision: a consent form nobody can read produces a signature, not a decision.

Where reform has happened

Several jurisdictions have restructured. Sweden’s mentorship system operates without removing legal capacity. Ireland’s Assisted Decision-Making (Capacity) Act replaced the nineteenth-century wardship system with a tiered arrangement built on presumed capacity. Peru abolished judicial interdiction outright, which is the most far-reaching reform any state has attempted and is watched closely in Europe for that reason. Several German-speaking systems reformed their guardianship law to strengthen the primacy of the person’s own wishes without abolishing representation.

The pattern in the successful reforms is the same: presumption of capacity as the default, support before substitution, decision-specific and time-limited measures where representation is unavoidable, and a duty to determine will and preferences rather than best interests.

Why this reaches beyond law

Article 12 is the hinge for a set of other rights. If legal capacity can be removed, so can the right to vote, which in several member states was tied directly to guardianship status until courts intervened. Consent to medical treatment, the right to choose where and with whom to live under Article 19, control over money and the ability to bring a complaint all rest on it.

That is why a guardianship order is rarely a single restriction. It is the doorway through which the others follow.
