That´s not quite true.
While A-L did not have the same state status as the rest of the empire they were represented in the parliament. .
At first they were not, ( as I said, administrated by the same ministry as Kameroun )
then, they were represented but the representative had no right of vote. ( and I think the first representatives were designated, not elected ).
Only after 1911, IIRC ( or was it 1907 ), were the representative of Elsass-Lothringen fully equal to the representatives of other landers. However, even then, I seem to remember that some administrative problem prevented them getting a full seat for some time.
And the 1913 Zabern incident showed even this to be a sham.
If you're interested, I'll look into my sources to give details and dates this evening.
