Final answer:
In legal writing, formal names of specific types of juries, such as 'Grand Jury' and 'Petit Jury,' should be capitalized, while more general terms like 'jury duty' are not typically capitalized unless part of a formal title.
Step-by-step explanation:
When referring to the kinds of juries in legal writing, it is standard to capitalize specific terms such as Grand Jury and Petit Jury when they refer to the formal names of those bodies. Terms like 'jury duty,' 'jury trial,' or simply 'jury' can typically be written in lowercase when they do not form part of a formal title or when they're used in a general sense. Correct capitalization is essential in legal documents to convey the appropriate level of formality and precision. For instance, 'The jury reached a verdict' or 'The members of the jury were selected from the pool of potential jurors.'
