There is a draft law being prepared for it to be passed and become a law. Even in the United States, the use of a mixer is considered legal, and all the problem that occurred because of Sinbad’s signature was because the address of the signature campaign for that mixer was included in the OFAC list, but you can still spend your coins to any party that does not support  OFAC lists, especially since most mining pools do not adhere to it.

unless there is a legal ban on these mixers in your country, and you are not using the mixer to hide illegal gains, then mixing your currencies is considered a legal act.
