Within a `CASE` statement, ensure that all possible outcomes return a boolean value. If a condition is not met and you don't provide an `ELSE` clause, the result will be `NULL`. Explicitly handle `NULL` cases by providing a default boolean value in the `ELSE` clause or by using `COALESCE` within the `CASE` statement itself.
