A silent coup in Poland?
But the decision of what is just and what is unjust will rest in new hands.
Only a few days after the swearing-in of the new Sejm - the lower house of the Polish parliament - the ruling PiS party pushed through both houses of parliament an amendment that would vindicate the president's legal maneuvering.
Representatives and senators of the PiS voted in an nighttime session to appoint replacements for five recently nominated constitutional judges.
Fairly cited academic article, doesn't use coup in title, but highlights that one person's "[constitutional] revolution through the ballot box" is another's "constitutional coup". Particularly when among the measures the constitutional court is [allegedly] packed and its old rulings [thus] undone.
De-democratization in Hungary: diffusely defective democracy
Never in the history of the European Union has an election in a member state resulted in political, legal, economic and administrative changes of this magnitude in such a short period.” For Orbán, this was a “revolution through the ballot box” while for others it amounted to a “constitutional coup d’état”. Freedom House continues to classify Hungary as a free country, but only barely. Between 2010 and 2016, Hungary deteriorated from the perfect score on political rights and civil liberties to the threshold of a partially free country. Hungary is in the top ten of countries where freedom has declined most in the past ten years, ranking between Venezuela and Nicaragua. [...]
The Constitutional Court, once one of the most independent and active in the region, has been packed by the government and stripped of many of its powers. To undo previous rulings against the Fidesz government, these were included in the new constitution itself. Jurisprudence based on the old constitution is no longer valid. By consequence, the Constitutional Court has stopped being an effective check on government.
Turkey’s Constitutional Coup
[...] the governing Justice and Development Party (AKP) put in place a set of constitutional amendments that effectively repealed the democratic character of the republic. And they accomplished this constitutional coup in the name of saving democracy. [...]
In retrospect, however, it was the AKP that regretted the judicial restructuring of 2010. Having strengthened the autonomy of the High Council of Judges and Prosecutors (HCJP) and limited the role of the executive in appointments, the government found itself blindsided in December 2013 by a criminal probe into cabinet ministers and their relatives on corruption charges being investigated by the very judges and prosecutors that were ushered in following the amendments.
Treating the investigation as an attempted judicial coup, and declaring that the judiciary had been infiltrated by its opponents from the Gülen movement, the government immediately introduced legislative changes to limit the powers of the Council while simultaneously removing or transferring hundreds of judges and prosecutors, replacing them with more reliable pro-government appointees. This legislation was manifestly unconstitutional and was eventually invalidated by the Constitutional Court, but since such rulings do not have retroactive effect the individuals reassigned or removed were not restored to their positions. Further legislative changes followed, not only reversing the gains in judicial autonomy from the 2010 amendment package, but politicizing judicial elections to the point of abrogating the independence of the judiciary altogether.
Almost everything [political] is a coup in Turkey :-0 I mean note the nice double meaning of "judicial coup" here.
While it's not uncommon to finds that [qualified] coup term in academic analyses (like the previous two quotes) or in opinion pieces in Western newspapers, I wasn't able to find much of an example of it being used so loosely by Reuters or AP in their news reporting. I suspect the reason is that AP's style book blog considers it improper in such a setting, given that they quote a stricter definition
a sudden, organized seizure of political power or an attempt by a faction or group to seize political power suddenly outside of the law.
Emphasis mine. Albeit that post relates to the US Capitol events in 2021; it doesn't explicitly touch on "constitutional coups".
OTOH Reuters did use "constitutional coup" quoted in a headline (relating to Nepal), when one of the actors involved used it. The Times of Israel coverage you've linked to is similar in that regard, i.e. "regime coup" is in quotes in the headline, and it's clearly attributed.
