Final answer:
The lawyer challenging Canada's new health regulations would assert the case is based on The Charter of Rights and Freedoms, which protects civil liberties potentially affected by these regulations. Complexities arise from the interaction between national policies and personal freedoms.
Step-by-step explanation:
The lawyer fighting the new regulations introduced by Canada's health minister preventing Health Canada from granting special permission for prescribing illicit narcotics such as heroin would likely argue that the case will rely on a) The Charter of Rights and Freedoms. The Charter of Rights and Freedoms is a vital part of Canada's Constitution that protects a variety of civil liberties and human rights, such as the right to life, liberty, and security of the person, which could potentially be infringed upon by such health regulations.
Issues around personal liberty, including the use of narcotics for medical purposes, involve complex legal and ethical considerations. National policies, such as those concerning drugs, override state laws where there might be contradictions due to the supremacy clause.
These types of cases invoke considerations of civil liberties, the right to make choices concerning one's body, and how they align with public health and safety regulations enforced by the government.
