The closing months of 2025 produced a dense run of judicial and regulatory decisions across four continents. Courts convicted a sitting prosecutor general, ordered governments to act on structural racism, and drew new battle lines between national sovereignty and supranational authority.

International Criminal Court rejects Israeli challenge

On December 15, 2025, the International Criminal Court rejected a request by Israel to suspend its investigation into alleged war crimes connected to the Gaza conflict. The prosecutor's inquiry will proceed despite Israel's objections. The decision landed days after the U.S. State Department announced, on December 18, sanctions on ICC judges and other officials involved in the same investigation — a move that sharpens the institutional standoff between Washington and The Hague.

The Court faces broader pressure as well. When ICC President presented the Court's 2025 report to the UN General Assembly on November 11, she noted that ratifications of the Rome Statute have climbed to 125 states, but flagged withdrawals from the statute, limited state cooperation in executing arrest warrants, and cyberattacks as persistent obstacles to the Court's mandate. On December 8, the ICC published its Strategic Plan for 2026–2029, setting out 10 strategic goals covering the delivery of justice, cooperation with states, victim-centered work, safeguarding of operations and institutional values, and enhanced risk management.

Europe: prosecutors convicted, marriages recognized, sovereignty tested

Spain's Supreme Court in Madrid found Prosecutor General Álvaro García Ortiz guilty of leaking confidential information in a case involving the partner of a leading opposition figure. The ruling imposed a two-year ban from office. García Ortiz resigned on November 24, saying he stepped down out of respect for the court, while signaling he may still appeal.

The Court of Justice of the European Union ruled on November 25 that all member states must recognize same-sex marriages performed in other EU countries when at least one spouse is an EU citizen. The court reprimanded Poland for refusing to recognize a marriage between two citizens concluded in Germany. For practitioners, the ruling means civil registrars across the bloc can no longer refuse recognition on national-law grounds in such circumstances.

The European Commission took a different sovereignty dispute a step further. On November 21, the EU opened an infringement procedure against Slovakia over constitutional amendments declaring national law supreme over EU law on cultural and ethical issues, including LGBTQ+ rights — the opening move in what may become a references-for-infringement showdown before the CJEU.

Italy's Supreme Court, on December 17, upheld the acquittal of Deputy Prime Minister Matteo Salvini in the migrant kidnapping case arising from his 2019 decision to block a rescue ship from docking. Migrant advocates condemned the ruling; Salvini and Prime Minister Giorgia Meloni praised it as validation of strict border enforcement.

United Kingdom: jury trial limits draw judicial caution

The British government announced on December 2 plans to curb jury trials in England and Wales by creating "swift courts," in which judges sitting alone would decide cases involving offenses carrying a potential sentence of three years or less. Ministers framed the measure as an emergency response to the criminal court backlog.

Lady Chief Justice Sue Carr declined to comment directly on the proposal but cautioned on November 24 that backlogs cannot be solved through structural reform alone. Reducing delays, she said, requires both procedural changes and sustained investment in judicial resources — a warning against treating jury trial reform as a substitute for funding, staffing, and courtroom capacity.

Asia and Africa: divergent rulings on marriage, and a new ICJ judge

A Tokyo High Court ruled on November 28 that Japan's ban on same-sex marriage does not violate the constitution, holding that civil law's definition of marriage falls within legislative authority and does not unlawfully discriminate. The decision cuts against a trend of lower-court rulings favoring marriage equality claims.

In India, 56 former Supreme Court and High Court judges publicly condemned a parliamentary impeachment notice against Madras High Court Justice G.R. Swaminathan on December 12. The former judges called the attempt to remove him over a controversial temple lamp ruling "anti-democratic" and warned it threatens judicial independence.

In Bangkok, judges from 13 Asia-Pacific countries gathered on November 20 to debate artificial intelligence in courts, emphasizing that AI tools must operate under human oversight and safeguards to support fairness in the justice system.

The UN General Assembly elected Phoebe Okowa of Kenya to the International Court of Justice on November 12.

Americas: Brazil recognizes structural racism; U.S. trials and sanctions

Brazil's Supreme Federal Court on December 19 officially recognized the existence of structural racism in Brazil and ordered the government to take action, including measures to reduce racial disparities in public services. The ruling came in a lawsuit brought by the Black Coalition for Rights and seven political parties seeking official acknowledgment of systemic racial discrimination — a holding that opens the door to structural, remedy-oriented litigation against the state.

In the United States, the trial of Milwaukee Judge Hannah Dugan is underway, centered on whether she unlawfully helped an undocumented immigrant avoid arrest by ICE at a courthouse. Observers widely view the prosecution as a warning to other judges who might interfere with federal immigration enforcement.

Capital punishment data from the Death Penalty Information Center, published December 15, shows a growing reluctance among capital juries to impose death sentences in 2025, even as executions nearly doubled to 48 — a surge driven primarily by Florida.

For practitioners across jurisdictions, the quarter's message is consistent: courts are asserting their authority against both political pressure and institutional resistance, while governments test the limits of judicial independence — and each ruling narrows the room for maneuver somewhere else.
