I suppose you refer to this: https://theconversation.com/why-romanias-election-was-annull...
"The Romanian constitutional court annulled the country’s presidential election on December 6.
This decision is unprecedented in Romanian history. It followed the declassification of documents by Romanian intelligence services that exposed evidence of voting manipulation through social media platforms, illegal campaign financing on TikTok, cyber-attacks orchestrated by external forces and suspected Russian interference."

> Here, the opposite could be alleged- that Romania took action, but the action was too immediate and drastic than was called for in the circumstances. Considering how the Court expressed a critical view of overly drastic measures in cases such as the above-mentioned Kermiova v Azerbaijan, it is possible that the Court could similarly show a disdain for the expeditious actions taken by the domestic judiciary in Romania.
Also apparently most voters voted this candidate because of economic reasos, not due to Russian proximity.
Establishment parties obviously didn’t like that outcome.
