The constitutional and doctrinal basis for capacity-based MAiD access.
Current Medical Aid in Dying (MAiD) frameworks in the United States and Canada rely on eligibility criteria—specifically "terminal illness" and "reasonably foreseeable natural death"—that are constitutionally fragile and doctrinally inconsistent with established medical jurisprudence.
This brief argues that decisional capacity is the only constitutionally robust eligibility standard. It develops three core legal arguments supporting this conclusion:
The law currently permits a competent adult to refuse a ventilator, causing death by suffocation, without requiring them to "try" other treatments first. Yet it prohibits the same adult from accessing pharmacological aid in dying until they have "exhausted" alternatives. This distinction is aesthetic, not principled.
State monopoly on the means of exit generates a duty to provide access.
The state has successfully monopolized the means of reliable, painless, and non-violent exit. Pharmacological agents such as pentobarbital are controlled substances; their possession without prescription is a crime. By criminalizing the only safe methods of ending one's life, the state has removed the individual's ability to exercise bodily sovereignty without state involvement.
Having created this monopoly, the state cannot claim neutrality. It is not merely "declining to assist"; it is actively blocking the exit. This creates a coercive condition: the individual is forced to either (a) continue existing against their will, or (b) resort to violent, traumatic, and uncertain methods that endanger the public and first responders.
When the state deprives an individual of the means to exercise a fundamental liberty interest—in this case, control over one's own bodily integrity and end of life—it assumes a corresponding duty to provide a lawful avenue to exercise that right. The state cannot ban the safe exit and then claim it has no obligation to provide it.
The doctrinal path runs through DeShaney v. Winnebago County, 489 U.S. 189 (1989). While DeShaney held that the state has no general affirmative duty to protect individuals from private harm, the Court explicitly preserved the "state-created danger" exception: where the state itself affirmatively created or enhanced the specific danger confronting the individual, a constitutional duty arises. Circuit courts have developed this exception across multiple circuits. (Stoneking v. Bradford Area School Dist., 882 F.2d 720 (3d Cir. 1989); Dwares v. City of New York, 985 F.2d 94 (2d Cir. 1993).)
Criminalization of the pharmacological means of exit is a paradigm case of state-created danger: the state's own regulatory act — the Controlled Substances Act and parallel state criminal statutes — is the proximate creator of the individual's constrained access. This is not a third party creating the danger; it is the state. The liberty interest at stake is the established constitutional protection of bodily integrity, which Cruzan v. Director, 497 U.S. 261 (1990), recognized as a liberty interest under the Due Process Clause.
Even under rational basis review, the monopoly-without-access structure is difficult to defend: there is no rational basis for criminalizing all reliable means of reliable exit and then denying regulated access to the population that would use it. The argument does not require identifying a new fundamental right. It operates as a duty-generating doctrine conditioned on what the state has already done.
Harmonizing MAiD eligibility with established treatment-refusal jurisprudence.
Medical jurisprudence is settled on the right to refuse treatment. A competent adult may decline life-saving antibiotics, dialysis, or ventilation. Crucially, they are not required to attempt the treatment first. A patient with a treatable infection may refuse antibiotics even if that refusal leads to certain death. The standard is informed refusal: does the patient understand the consequences?
Current MAiD laws, however, often require applicants to have "exhausted" reasonable treatments or to be in an "irremediable" state. This imposes a higher burden on the active choice (MAiD) than on the passive choice (treatment refusal), even though the outcome (death) and the agent (the patient) are identical.
Opponents argue that in treatment refusal, the disease causes death, whereas in MAiD, the drug causes death. This is a legal fiction. When a stable patient orders a ventilator removed, the immediate cause of death is the action of removal. If a third party removed the ventilator without consent, it would be homicide. We permit the removal not because the disease is the agent, but because the patient's autonomy is paramount.
Conclusion: If capacity is sufficient to authorize the removal of life support, it is sufficient to authorize MAiD. The requirement should be Informed Refusal of alternatives, not the Exhaustion of them.
Process as functional evidence of capacity.
A primary objection to expanding MAiD eligibility is the fear of impulsive suicidality—that a person in a transient crisis will make an irreversible decision. This objection fails to appreciate the nature of the proposed assessment protocol.
Impulsivity is characterized by an inability to sustain goal-directed behavior over time against obstacles. The proposed MAiD assessment process—a 90-day waiting period, multiple independent interviews, mandatory paperwork, and bureaucratic navigation—is a series of obstacles.
A person in a transient, reactive crisis rarely possesses the executive function to navigate a three-month bureaucratic maze. They drop out, or the crisis resolves. Conversely, an applicant who methodically navigates this process, attends every appointment, and maintains a consistent preference across 90 days has demonstrated precisely the kind of stable, executive capacity that distinguishes autonomous preference from impulsive reaction.
The process is the filter. The bureaucracy itself functions as a diagnostic stress test for decisional stability.
Any US constitutional argument in this domain must engage Washington v. Glucksberg and Vacco v. Quill. This framework does so directly.
Washington v. Glucksberg, 521 U.S. 702 (1997), held that there is no fundamental right to physician-assisted suicide under the substantive Due Process Clause; the right asserted was not "deeply rooted in this Nation's history and traditions" under the Court's unenumerated rights methodology. Vacco v. Quill, 521 U.S. 793 (1997), its companion, held that the equal protection clause does not require treating treatment refusal and assisted dying identically, because the distinction between letting die and causing death survives rational basis review.
Three structural points clarify why this argument is not foreclosed by these holdings.
The Constitutional Pincer is not an assertion that there is a fundamental right to assisted dying. It is a state-created-danger / positive duty claim: the state has monopolized the means of exit and thereby assumed a corresponding obligation. Glucksberg addressed whether a new fundamental right exists; the Pincer argues that a duty arises from what the state has already done. These are distinct constitutional theories. Glucksberg does not foreclose the latter.
Glucksberg applied its "deeply rooted" test to a narrowly characterized right: "right to commit suicide with assistance of a physician." Under Obergefell v. Hodges, 576 U.S. 644 (2015), the Court applied a broader framing to dignity-based liberty interests. Bodily integrity — the right to determine what happens to one's own body — is unambiguously deeply rooted (Cruzan). The Pincer engages this established right, not a novel one. The state has interfered with that established right by removing the means of its exercise, generating the duty at issue.
Vacco's equal protection holding rests on the claim that the distinction between treatment refusal and assisted dying has a rational basis because "the disease kills" in the former case. The Causation Fiction argument (Argument II, above) exposes this as a legal fiction: when a stable patient orders a ventilator removed, the immediate cause of death is the active step of removal. Vacco's rational basis disappears if the factual premise supporting it is false. The rational basis standard requires a legitimate reason for the distinction; a reason dependent on a legal fiction is not legitimate.
The practical consequence for US advocacy: the Constitutional Pincer is strongest as a supplementary argument to a primarily legislative campaign. The constitutional path is available but would require sustained litigation development. The legislative path — state-by-state Death with Dignity reform — does not require Glucksberg to be overruled; it requires state legislatures to adopt the capacity standard directly, bypassing constitutional compulsion entirely. This framework is designed for both tracks.
Proposed legislative text with doctrinal commentary.
| Provision | Proposed Text | Doctrinal Commentary |
|---|---|---|
| Eligibility Standard | Any adult person who demonstrates decisional capacity as assessed under this Act. Terminal diagnosis and proof of suffering are not required. | Removes the "suffering" criterion, which is subjective and clinically incoherent, replacing it with "capacity," which is a functional and adjudicable standard. |
| decisional capacity | The ability to understand the nature of the decision, appreciate its consequences, and communicate a stable preference. A history of psychiatric diagnosis does not constitute disqualification. | Codifies the standard from Starson v. Swayze (Canada) and US competency law: capacity is a functional assessment of the present state, not a diagnostic category. |
| Informed Refusal | An applicant need not have utilized any alternative prior to application. Documented informed awareness of alternatives and reasons for declining them shall satisfy this element. | Harmonizes MAiD with the Informed Refusal doctrine governing treatment rejection. Comprehension is required; compliance is not. |
| Assessment Period | A minimum of 90 days from first application for non-terminal provisions. Multiple independent evaluations required. | Operationalizes the "Bureaucratic Stress Test." The duration serves as a filter for transient states and impulsivity. |
| Socioeconomic Reporting | Where inadequate housing, income, or support is a driver, the authority must transmit a formal signed report — attested by the provider, the applicant, and an independent witness — to the Ministries of Health and Social Services and the Regional Coroner. | The "structural accountability mechanism." Creates political accountability for structural failures without violating the individual's right to exit. |
| Evaluator Disagreement | Where independent evaluators reach divergent conclusions on the presence of decisional capacity, the matter is referred to an independent Clinical Ethics Committee within fourteen days. A finding of capacity requires reasoned concurrence by at least two evaluators. Unresolved disagreement triggers referral to the administrative review panel under §[N]. | Addresses a governance gap present in all comparable frameworks. Comparable to the SCEN second-opinion mechanism in the Netherlands and the KNMG consultation pathway for contested cases. |
| Standard of Proof | Decisional capacity must be established by clear and convincing evidence across the full assessment period. This standard applies to each of the four functional elements. The burden of establishing capacity rests on the assessment record, not on the applicant to disprove incapacity. | Consistent with the "clear and convincing" standard applied in US guardianship and competency determinations (Cruzan; In re Conservatorship of Wendland, 26 Cal.4th 519 (2001)). Reflects the gravity and irreversibility of the decision. |
| Review and Appeal | Any applicant whose request is denied following assessment has the right to: (a) request a fresh independent evaluation by a new panel within 30 days; (b) seek expedited review by the administrative tribunal within 60 days of any adverse panel decision; and (c) pursue judicial review of any adverse tribunal decision. Denial decisions must be in writing with reasoned findings. | Standard administrative law architecture. Absence of a review mechanism in comparable frameworks has been identified as a governance deficit. Reasoned written denials create the evidentiary basis for meaningful appellate review. |
