What is the correct preposition for this sentence?

[Justine A.]

Hello Sir Joe!

What should be the appropriate preposition in this sentence for this Court Order: "Considering that the Honorable Public Prosecutor assigned in this court is presently attending a seminar, the Arraignment and Pre-Trial Conference is reset ____ 29 August 2018 at 8:30 in the morning, as previously scheduled."

My supervisor told me it should be the preposition "to" and not "on." Which is which? Also, is the auxiliary verb "is" correct to use if the subject is "Arraignment and Pre-Trial Conference"?

Your supervisor is correct in choosing the preposition “to” instead of “on,” since the verb “reset” denotes a movement or action or condition suggestive of movement from one date and time to another, “29 August 2018 at 8:30 in the morning”—which, of course, is the object of the preposition “to”: “... the Arraignment and Pre-Trial Conference is reset to 29 August 2018 at 8:30 in the morning, as previously scheduled."

On the other hand, the preposition “on” would be appropriate if the verb is, say, “is now scheduled,” as it would simply indicate a time frame during which something is going to take place. In this case, the date and time of the proceedings—“29 August 2018 at 8:30 in the morning”—would be the object of the preposition “on”: “...the Arraignment and Pre-Trial Conference is now scheduled on 29 August 2018 at 8:30 in the morning, as previously announced.”

If the term “Arraignment and Pre-Trial Conference” is considered one and the same procedure, which is strongly implied by the statement, then the linking verb should be the singular “is”; however, if the term is being used to refer two separate, distinct, and independent activities, then the use of the plural “are” would be called for.
