McHUGH, J. July 15, 2026 MEMORANDUM This is a discovery dispute on appeal from the United States Bankruptcy Court for the Eastern District of Pennsylvania. In an adversary proceeding, Plaintiffs, Appellees here, Chia-Hui Chang and Pai-Chi Tsai (“Plaintiffs”) sought to recover debts allegedly owed to them by Defendant Liljana Sinojmeri and her business collaborators (“Defendants”), whom the Plaintiffs believe committed fraudulent transfers to evade their creditors. To discover possible aliases used in those transfers, Plaintiffs served a subpoena on the Appellant, Mario Martinez Aguila (“Martinez”),1 whom Plaintiffs understood had employed Defendants around the time of the bankruptcy filing. Martinez has resisted the subpoena for over a year. His methods have included filing a series of motions to quash or modify the subpoena and impose a restrictive protective order. The Bankruptcy Court rejected Martinez’s motions and ultimately ordered contempt sanctions and

He now appeals the Bankruptcy Court’s orders around the subpoena, focusing his issues on the order denying his Motion to Quash

and the order granting contempt sanctions and attorneys’ fees. On each issue Martinez raises, I will affirm the Bankruptcy Court. I. Factual Record This litigation began when Plaintiffs hired Defendants’ company, American Steel Contractors (“ASC”), to work on Plaintiffs’ house, after which Plaintiffs say Defendants committed extensive fraud. See Appellee’s App. at 46-47, ECF 15-1. Plaintiffs first sued Defendants in Pennsylvania state court. See id. Two years later, ASC filed for Chapter 7 bankruptcy in the Bankruptcy Court of the Eastern District of Pennsylvania. See id. at 48-49. Defendants’ bankruptcy filings represented that Defendant Sinojmeri had 100% ownership of ASC, that the company had a value of $0, and therefore that she had no assets to fulfill its debts.

See Appellant’s App. at 139-42, ECF 13-1. Despite this claimed insolvency, Plaintiffs observed that Defendants, supervised by Defendant Sinojmeri’s son-in-law Ilir Sevi, had continued a monthslong construction project on the home of their next-door neighbor, Mario Martinez Aguila. See Appellee’s App. at 47. Plaintiffs then filed an adversary proceeding in the Bankruptcy Court seeking to prevent discharge of Defendants’ debts, alleging that the Defendants had committed some number of fraudulent transfers, shifting the original company’s money and client lists among various business aliases to hide it from creditors including the Plaintiffs. See id. at 51. To investigate Defendants’ potential aliases, Plaintiffs served a subpoena on Martinez

based on the work they had seen Defendant Sinojmeri’s son-in-law doing at Martinez’s home. See id. at 53. The subpoena sought 11 forms of records:

2 1. A complete copy of all documents, as defined below,2 relating to communications with Ilir Sevi, Liljana Sinojmeri, American Steel Contractors LLC (hereafter “ASC”). or any person or entity affiliated with any of the foregoing.
