The Spiegel affair in 1962 caused the coalition to fall apart over Defence Minister Franz Josef Strauss' actions which violated press freedom, leading to all FDP ministers resigning in protest.
As a result, the cabinet was a minority government of the CDU/CSU for just under a month in the fall of 1962 before Adenauer was able to convince the FDP to return to the coalition by assuring Strauß' resignation.
Shortly after the Spiegel affair, the resignation of Defence Minister Franz Josef Strauss was required to gain back the FDP's support for the cabinet, leading to a reshuffle.
The government still drew its constitutional legitimacy from Adenauer's election on 14 November 1961.
Adenauer decided to retire just a few months later, following which Ludwig Erhard was elected as Chancellor and formed the first Erhard cabinet on 17 October 1963.
