Counterclaim for revocationPublic
Summary: The rapporteur deferred the claimant's lateness objection (R. 9.2 RoP) regarding allegedly new factual submissions in the respondents' reply brief on the amendment request, ruling it a substantive matter for the full panel to decide at or after the oral hearing. The claimant was granted three weeks (until 19 May 2026) to respond to the contested submissions in the interest of equality of arms, after which the written procedure is closed.
