Final answer:
Tax treatises and journal articles should be used in the formation of a practitioner's research schedule in the field of law. They provide valuable insights into legal principles, court decisions, and interpretations of tax laws.
Step-by-step explanation:
In the formation of a practitioner's research schedule in the field of law, tax treatises and journal articles should generally be used. These sources provide valuable insights into legal principles, court decisions, and interpretations of tax laws. However, it is important to note that these sources should be used alongside primary legal sources, such as statutes and regulations, for a comprehensive understanding of the law.
While tax treatises and journal articles may not serve as advocates for specific client groups or provide practical insights into family behavior, they play a vital role in legal research and analysis. They help practitioners stay updated on changes in tax laws, understand legal precedents, and access scholarly analysis of complex legal issues. Therefore, they are valuable resources that should be considered in the formation of a practitioner's research schedule.
