Case briefing

What the Bureau knows

Adrian Mercer boarded Northstar Railway Train 417 with a ticket for Seat B-12. His belongings arrived. He did not. The Bureau closed the file after a single review, then reopened it when a later clerk found that two of its documents could not both be true. The dossier is presented as it was archived: complete, contradictory and unresolved.

Background

The file originates in Northstar Railway — Train 417 and passed through three administrative reviews without a determination. Records were copied by hand at least once, and the transcription differs from the original in ways the archive never reconciled. Nothing in this dossier has been corrected for you.

Official investigation question

On the evidence contained in this dossier, what is the most defensible account of what happened, and which document must be wrong for that account to hold?

Known facts
  • The file is registered under reference OB-417-2006-1126.
  • 27 evidence items are catalogued in the dossier.
  • At least two documents disagree on the recorded sequence of events.
  • One recovery entry has no responsible officer named.
  • No determination of responsibility was ever entered.
Unresolved questions
  • Which of the two conflicting chronologies is supported by physical material?
  • Why was the file re-sealed after its second review?
  • Who authorised the movement recorded without a signature?
  • What was removed between the original folder and the copied one?
Your objective

Read the dossier, establish a chronology you can defend, identify the contradiction the Bureau overlooked, and submit a reasoned resolution.
