- Facts of the case
- Montgomery v Lanarkshire of 2015 is an English tort law case regarding informed consent.
- The claimant, Nadine Montgomery, was a diabetic woman of small stature
- She suffered from birth injuries when delivering her baby vaginally
- Nadine Montgomery’s baby suffered severe disabilities following the birth including shoulder dystocia and cerebral palsy
- She claimed the medical professionals did not inform her of the potential risks or of an alternative procedure for giving birth
- Issues Raised
- Montgomery sued the doctors for negligence as they failed to inform her of the risks involved with being a small, diabetic woman delivering a larger baby vaginally.
- Failure to inform the patient of the risks to giving birth vaginally
- Failure to inform the patient of potential birth injuries to be sustained
- Failure to give patient the choice with recommended process or procedure
- Arguments of the parties
- Key contentions by the Plaintiff
-Nadine Montgomery argued that her doctors were negligent
-The Doctors failed to inform her of the risks associated with giving birth vaginally
-Therefore, she could not make an informed decision about her delivery method
- Key contentions by the Defendant
-Argued that many medical professionals are concerned that disclosing too much information or too many options would overwhelm patients with information they may not understand
-Thus, causing distress or poor decision making
- Judgement/Final decision making
- The Court of United Kingdom released judgement in the Favor of Nadine Montgomery in March of 2015
- The court, emphasized that it is necessary to explain information in a way the patient can understand
- The case was deemed a conflict of standards – informed consent versus medical preference
- The Court affirmed the requirement for informed consent based on this duty of disclosure, setting a significant precedent in medical law
- Legal Reasoning/Ratio Decidendi
- Through this case, the court mandates that medical practitioners must fully disclose materially relevant risks and benefits of treatment to patients, even those considered small, to ensure valid informed consent
- Informed consent must be clarified and align with ethical guidance for doctors
- As of today, the Montgomery Test has been applied in several cases in the United States surrounding consent and medical ethics
- The case also established the “Montgomery principle,” which shifted the standard for informed consent from the “reasonable doctor” (the Bolam test) to the “reasonable patient”
- Conclusions/Observations
- This case has now created a patient-centred approach, emphasizing patient autonomy in making informed choices about their own bodies
- Key aspects of the Montgomery Principle- Duty of Disclosure, Materiality, Informed Choice/Consent, Shift in Standard
- Mistakes such as improper labor management or insufficient fatal monitoring not only threaten the newborn’s health but also impose emotional and financial strains that may persist for generations.
- Doctors have a duty to inform patients of the risks involved in any procedure
- Failing to do so could make them liable if a patient is injured
