In this AI-powered episode of UPC Unfiltered, get the key takeaways from a dense week of UPC caselaw. Our digital hosts discuss Prof. Willem Hoyng's Unfiltered analysis of 12 new decisions on costs, withdrawals, and procedural discipline.

Highlights from this episode include:

• Security for costs: Learn when significant security can be required, based on factors like NPE status or difficulties enforcing costs abroad, and how failure to provide it can lead directly to a default judgment.

• Cost orders: We discuss why withdrawing a claim triggers a mandatory cost procedure that can lead to an expensive cost order. However, the court also clarifies that “unnecessary” expenses are not reimbursed, nor are the costs for the cost procedure itself.

• Warning on procedural conduct: Hear about a sharp warning from a Judge-Rapporteur against playing games, confirming a party’s representative in the main action can’t evade service of an anti-anti-suit injunction (AASI) by arguing they weren’t instructed.

• Auxiliary requests for dependent claims: The Mannheim Local Division repeats a crucial point: if you want to defend dependent claims after claim 1 is found invalid, an auxiliary request is necessary. Simply relying on the granted claims is not enough.
