Contemporary historical accounts reproduced by the Universitätsbibliothek Mannheim place the attempted closure after Hardenberg’s death in late 1822 and the royal rejection in January 1823.

• In Rudolf Lantzsch’s Zur Geschichte des Deutschen Reichsanzeigers und Preußischen Staatsanzeigers it states that, after Hardenberg died in November 1822, the ministry proposed at the beginning of 1823 that the Staatszeitung be discontinued, and that King Friedrich Wilhelm III rejected this in a cabinet order dated 12 January 1823.
• Lantzsch’s later jubilee article says the same thing: after debate within the ministry, “In der Kabinettsordre vom 12. Januar 1823 lehnte der König indes den Antrag ab”.

So the article’s wording that this happened in January 1832 is not just approximate; it conflicts with the documented year in the historical record. The correct date is January 1823.

The sentence places Napoleonic occupation in a “preußisch-deutschen Reich”, but that polity did not exist at the time.

Authoritative historical overviews place the relevant state forms as follows:

• Prussia was a kingdom that later became the largest state in the German Empire.
• The German Empire (Deutsches Kaiserreich) was founded only in 1871.
• After Napoleon’s defeat, Germany was organized as the Deutscher Bund (German Confederation) from 1815 to 1866, a confederation of sovereign states rather than a unified Reich under Prussia.

So for the Napoleonic period, it is accurate to refer to Prussia or to the German states / Deutscher Bund (depending on the date), but not to a “preußisch-deutsches Reich.”
