43 U.S.C. § 106 — Continuing taking of depositions in behalf of opposite party

This section lets the other side in a case take its own depositions right after the first side finishes. Once the depositions described in section 105 of this title are concluded, the opposite party may immediately begin taking depositions of its own, at its own expense. These depositions happen at the same time, at the same place, and before the same officer as the first party's depositions. There is one condition. Before starting, that party must first give notice to the opposing party — or to any agent or attorney representing the opposing party in the deposition process — that it intends to take its own depositions.
