And, let's say, the Court also hasn't been exactly non-partisan lately either (if it reminds you some other country, then you are right, these things can happen anywhere). So, many people were very unhappy with such situation, where a largely self-perpetuating body (the Court controls a lot of appointment process too) has nearly infinite power over the elected officials.
Given that one major party (or rather coalition, but let's not get into the weeds) has lost the elections, but enjoys the power in the Court, and the other has the majority in the parliament, but has their actions constantly blocked by the Court with motivations like "it doesn't look reasonable to us", the inevitable readjustment happens. It does not mean at all the Court - or any courts - lost all ability to review the decisions of the government, far from it. It just means that use of that particular tool - declaring any decision "unreasonable" and be done with it - has been restricted. Of course the side that enjoyed using that tool doesn't like it at all. But the Court still has all the power of review that it had using any other tools - including all the laws previously passed and those Basic Laws that exist. It just moved from "infinite power" to "limited power".
