Here's why:
* It's a common phrase: "Pre-trial conference" is a standard legal term, not a proper noun.
* It's not a specific event: While there might be a specific pre-trial conference, the term itself isn't unique or formal enough to warrant capitalization.
Examples:
* Incorrect: We will attend the Pre-Trial Conference on Friday.
* Correct: We will attend the pre-trial conference on Friday.
* Incorrect: The judge set the Pre-Trial Conference for next week.
* Correct: The judge set the pre-trial conference for next week.
Exceptions:
* Formal Titles: If "Pre-Trial Conference" is part of a formal title (like a document title), you would capitalize it. For example: "Order Setting Pre-Trial Conference."
* First Word of a Sentence: As always, you capitalize the first word of a sentence.
