The Boston Globe argued in a court filing Wednesday that it cannot complete its investigation into a harassment accusation against its editor, Brian McGrory, without a court order compelling the former Boston.com employee who made the allegation to answer questions and provide relevant information.

The Globe is seeking an injunction against the former Boston.com writer and editor, Hilary Sargent, who wrote on Twitter last month that McGrory sent her an inappropriate text. The newspaper has argued that Sargent’s separation agreement from the company requires her to cooperate with an investigation arising from her employment.

The case is scheduled for a hearing Thursday in Suffolk Superior Court.

In court filings this week, Sargent said she did not have the original text exchange and could not say if it occurred during her employment at the Globe-owned website, where she worked from 2014 to 2016. Her filing said the screenshot she posted on Twitter was indicative of “inappropriate and sexually suggestive’’ messages McGrory sent her while she worked at Boston.com. The filing did not provide other text messages.

McGrory has denied harassing Sargent and has said he is fully cooperating with the Globe’s inquiry.

Sargent included in her own filing copies of e-mails she sent to top Globe managers in late 2017, urging the paper’s leadership to examine how women have been treated within its own ranks and offering to discuss the issue. She has said she did not get a response.

In Wednesday’s filing, the Globe said it “has done all of the investigation it can without [Sargent], both internally and through an outside investigator; it has interviewed McGrory multiple times, and reviewed every available document, email, and text message. For now, at least, one critical step remains: hearing from the complainant herself.’’

“She may possess facts that no other witness has — her understanding of her relationship with McGrory, for example — which can only come from her,’’ the newspaper asserted. “And she may well possess information — emails and text messages — that the Globe has been unable to obtain from McGrory.’’

“The sole available remedy is also a very simple one: requiring Sargent to be interviewed and to provide relevant information — the same thing the Globe, or any employer, would ask of any person claiming to have been a victim of harassment by a fellow employee,’’ the Globe wrote.

The newspaper filed its complaint last month, days after Sargent posted a screenshot of a text exchange in which one of the parties asks the other, “What do you generally wear when you write?’’ The screenshot does not identify the parties or indicate the date of the exchange, but Sargent later wrote that the text came from McGrory. In an accompanying tweet, she wrote: “Don’t respond to a female employee who is asking for advice about writing with an inquiry about what she wears while she attempts to write. Just. Don’t.’’

Sargent, through her lawyer, Jack Siegal, declined to comment Wednesday on the Globe’s latest filing.

McGrory has recused himself from oversight of the Globe’s coverage of the allegations and the related lawsuit.
