Background
T-Mobile stockholder David Dinkevich brought class and derivative claims arising from T-Mobile US, Inc.’s 2020 merger with Sprint Corporation and later transactions through which Sprint’s former controlling stockholder, SoftBank Group Corp., monetized much of the T-Mobile stock it received. The complaint alleges that T-Mobile’s controlling stockholder, Deutsche Telekom AG, caused T-Mobile to proceed with the merger on unfair terms and later facilitated transactions that provided non-ratable benefits to Deutsche Telekom and SoftBank.
After extensive portions of the Second and Third Amended Complaints and related filings were sealed, Handelsblatt journalist Phillip Alvares de Souza Soares challenged their confidential treatment under Court of Chancery Rule 5.1. Most defendants withdrew their redactions, but SoftBank, Marcelo Claure, and Ronald Fisher sought to preserve redactions in specified complaint paragraphs and to maintain confidential treatment for all versions of expert Benjamin Sacks’s report. The matter was assigned to Magistrate in Chancery Christian Douglas Wright for a final report resolving the challenge.
The Court’s Holding
The magistrate recommended denying continued confidential treatment for the challenged complaint allegations. Rule 5.1 presumptively makes court records public and required the SoftBank defendants to show, among other things, that disclosure would cause particularized harm. Their generalized assertions that the material involved proprietary strategies or sensitive personal and financial information did not supply the required tangible evidence of concrete damage.
The magistrate found additional reasons for disclosure: some assertedly proprietary material amounted to banter or boasting, duplicated information already public or unredacted, or concerned events and investments that had become stale. The loan-negotiation allegations could not remain sealed merely because other public information might already be sufficient to understand the dispute, and the allegations concerning Claure and Fisher were not protected simply because they were personal, previously private, or potentially embarrassing.
The magistrate recommended granting continued confidential treatment for all versions of the Sacks Report, relief the journalist did not oppose. That recommendation was consistent with an earlier order that had struck specifically the July 30, 2026 updated Sacks Report and references to that updated report in the Third Amended Complaint. The decision was a Final Report under Court of Chancery Rule 144, with exceptions due November 4, 2026.
Key Takeaways
- Rule 5.1’s strong presumption of public access requires concrete evidence that disclosure will cause particularized harm; conclusory claims of business or personal sensitivity are insufficient.
- Information does not qualify for sealing merely because it was private, could be embarrassing, or is unnecessary to understand the litigation, and age or changed circumstances may eliminate any remaining sensitivity.
- The magistrate recommended unsealing the challenged complaint allegations while preserving confidentiality for all versions of the Sacks Report; only the July 30, 2026 updated report and related complaint references were identified as having previously been struck.
Why It Matters
The report reinforces the demanding burden imposed on parties seeking to shield Delaware court filings from public view. Parties must identify specific harm supported by tangible evidence, not rely on labels such as “proprietary,” “personal,” or “financial.”
It also clarifies that public access is not limited to information strictly necessary to understand a dispute. Once material is filed on the docket, the presumption favors disclosure unless every applicable requirement for confidential treatment is met.
