1. Core Legal Principles Governing Medical Decision Planning

Across jurisdictions, courts generally recognize:

(A) Bodily autonomy is paramount

No medical treatment can be forced without valid consent.

(B) Competent adults decide for themselves

Spouses do not automatically override each other’s medical decisions.

(C) Substitute decision-making applies only when capacity is lost

Courts rely on:

• Healthcare proxies
• Advance directives
• “Best interests” standard

(D) Marriage does not equal medical guardianship

A spouse may be consulted, but does not always have final authority unless legally appointed.

2. Common Dispute Scenarios in Marriage Preparation

1. Disagreement on life support removal

One partner wants withdrawal; other insists on continuation.

2. Religious objections

E.g., refusal of blood transfusions.

3. Fertility and reproductive control

IVF, abortion, contraception disagreements.

4. Emergency ICU decision conflicts

Family vs spouse vs hospital ethics committee.

5. End-of-life directives not aligned

One partner refuses to execute living will.

6. Lack of legal proxy designation

Leading to court-appointed guardianship disputes.

3. Key Case Laws (International + India)

1. Schloendorff v. Society of New York Hospital (1914)

This foundational U.S. case established that:

“Every human being of adult years has a right to determine what shall be done with their own body.”

Relevance:
Forms the basis of informed consent doctrine. In marriage disputes, even spouses cannot override bodily autonomy.

2. Canterbury v. Spence (1972, U.S.)

The court held that doctors must disclose material risks to patients.

Relevance:
Supports the idea that decision-making belongs to the patient, not family members, unless delegated.

3. Cruzan v. Director, Missouri Department of Health (1990, U.S.)

Recognized that:

• Patients have a constitutional right to refuse treatment
• Clear and convincing evidence is required to withdraw life support if patient is incapacitated

Relevance:
In marital disputes, courts require strong proof of the patient’s wishes before allowing spouse to withdraw treatment.

4. Airedale NHS Trust v. Bland (1993, UK)

Allowed withdrawal of life support from a patient in a persistent vegetative state.

Relevance:
Established that continued treatment must be in the patient’s best interests, not family preference alone.

5. Re T (Adult: Refusal of Treatment) (1992, UK)

Held that:

• A competent adult may refuse treatment even if it leads to death
• But consent may be invalid if influenced improperly (family pressure, confusion)

Relevance:
In marriage preparation, courts scrutinize whether a partner’s refusal was truly voluntary.

6. Montgomery v. Lanarkshire Health Board (2015, UK Supreme Court)

Shifted medical law toward patient-centered disclosure.

Relevance:
Strengthens autonomy and reinforces that spouses cannot assume authority over medical risk decisions.

7. Aruna Shanbaug v. Union of India (2011, India Supreme Court)

Recognized passive euthanasia under strict conditions.

Relevance:
Set precedent for withdrawal of life support based on best interests and medical ethics, often requiring court supervision when family disputes arise.

8. Common Cause v. Union of India (2018, India Supreme Court)

Legalized advance directives (living wills).

Relevance in marriage disputes:

• A spouse cannot override a valid living will
• Courts may appoint guardians only when no directive exists

9. Gian Kaur v. State of Punjab (1996, India Supreme Court)

Held that right to life does not include a general right to die, but recognized dignity in death discussions.

Relevance:
Forms constitutional background for end-of-life medical disputes in marriage contexts.

10. Suchita Srivastava v. Chandigarh Administration (2009, India Supreme Court)

Recognized reproductive autonomy as part of personal liberty under Article 21.

Relevance:
Directly applies to marital disputes involving:

• abortion decisions
• contraception choices
• reproductive medical planning conflicts

4. How These Disputes Arise Before Marriage

Medical decision planning disputes often appear during marriage preparation when couples:

• Draft prenuptial or cohabitation agreements including medical clauses
• Decide on healthcare proxies
• Discuss religious or ethical incompatibility
• Plan for fertility treatments or chronic illness management
• Attempt to define “spouse decision authority” informally (which may not be legally enforceable)

5. Legal Position: Can Spouses Pre-Agree on Medical Authority?

Generally:

Valid:

• Appointment of healthcare proxy
• Advance directives
• Consent for emergency contact hierarchy
• Shared medical planning agreements

Potentially invalid:

• Clauses that permanently waive bodily autonomy
• Agreements forcing medical treatment acceptance
• Binding future consent without capacity safeguards

Courts typically refuse to enforce contracts that:

• violate public policy
• override personal liberty
• restrict fundamental medical rights

6. Conclusion

Marriage preparation medical decision disputes arise because marriage creates emotional expectations of authority, but law preserves individual bodily autonomy. Courts consistently prioritize:

• informed consent
• prior expressed wishes
• patient autonomy
• best interests standard (only when no clear directive exists)

The central legal tension is:

Marriage creates relational closeness, but not automatic medical control.
