Maybe an explanation why alone Mr.Kohl's refusal to name the
donators is more or less a criminal offense (of course
the politicians took care that it is one which has no
punishments associated with it):
Article 21 of the German constitution states that (my
translation): "Political parties [...] have to give public
account of source and usage of their resources as well as their
wealth."
When becoming German chancellor Mr. Kohl had to swear an
oath, which contains according to article 56 of the constitution
the following "I vow [...] to protect and observe
constitution and federal laws [...] ."
So Mr. Kohl is putting his "word" higher than the German
constitution and thereby breaching constitution and his oath at the same time.
Also, non-acceptance of the constitution is in Germany a ground for
dismissal as civil servant. Mr. Kohl as former head of all civil
servants is now really a role model for his former subordinates. Despite all this he is still trying to stylize himself as martyr.
