German journalism has a written code of good practice, the Pressekodex of the German Press Council. It was handed to Federal President Gustav Heinemann on 12 December 1973. By tradition, every later change is also handed to the sitting Federal President. One of its most debated rules concerns whether to mention the ethnic or national group of a suspect. In 2016 several editors called for this guideline to be deleted. The Council did not delete it. On 22 March 2017 it rewrote guideline 12.1. It now says that membership of a group soll in der Regel nicht erwähnt werden, es sei denn, es besteht ein begründetes öffentliches Interesse, should as a rule not be mentioned unless there is a justified public interest.
