German parliament could charge its members (9)

I believe the answer is:

reichstag

I'm a little stuck... Click here to teach me more about this clue!

'german parliament' is the definition.
'reichstag' can be an answer for 'parliament' (I have seen 'European parliament' mean 'reichstag' so perhaps 'parliament' could also mean 'reichstag'). I am not certain of the 'german' bit.

'charge its members' is the wordplay.
'charge its' can be anagrammed to 'REICHSTAG'.
Though, I am not clear how the anagram is indicated.

'could' is the link.

Can you help me to learn more?

(Other definitions for reichstag that I've seen before include "Berlin building burnt in 1933" , "Continental diet" , "Former German parliament" , "Berlin parliamentary building" , "diet in Germany" .)

I've seen this clue in the Sydney Morning Herald.
