Final answer:
The assertion is false; cases in Lexis Advance include LexisNexis Headnotes, which are created by legal editors to summarize key legal points in a case, assisting users in understanding and researching legal doctrines efficiently.
Step-by-step explanation:
The statement that cases in Lexis Advance do not have LexisNexis Headnotes is false. Lexis Advance is a comprehensive legal research platform that does include LexisNexis Headnotes for cases. These headnotes provide summaries of the legal points discussed in the case and are crafted by legal editors. They help practitioners, students, and scholars quickly understand the key points and relevant legal doctrines of a case without needing to read through the full text.
It's important when using Lexis Advance or any other legal research tool to be familiar with these features, as they can significantly aid in legal research and case analysis.
