I have some experience in this having done a protest myself. The prophet (pbuh) did a protest once, where he cut down palm trees. This is in the Quran and the noted down in the life of the prophet.
What you O Muslims cut down of a palm tree of the enemy or you left it standing on its stem it was by the Leave of Allah, and in order that He might disgrace the Fasiqun (59:5).
It is narrated on the authority of 'Abdullah that the Messenger of Allah (may peace be upon him) ordered the date-palms of Banu Nadir to be burnt and cut. These palms were at Buwaira. Qutaibah and Ibn Rumh in their versions of the tradition have added: So Allah, the Glorious and Exalted, revealed the verse:" Whatever trees you have cut down or left standing on their trunks, it was with the permission of Allah so that He may disgrace the evil-doers" Sahih Muslim 19:4326
The Quran explains that in law there is a balance. This means that although the prophet (pbuh) was cutting down the trees, he was doing it to counteract his enemies oppressing the Muslims. This balance is mentioned in the Quran:
We verily sent Our messengers with clear proofs, and revealed with them the Scripture and the Balance, that mankind may observe right measure; and He revealed iron, wherein is mighty power and (many) uses for mankind, and that Allah may know him who helpeth Him and His messengers, though unseen. Lo! Allah is Strong, Almighty. (57:25)
As for the sky, He raised it ˹high˺, and set the balance ˹of justice˺ (55:7)
That you be not defiant in the Balance. (55:8)
So establish weight with justice and fall not short in the balance.(55:9)
You would be surprised that this is also English law. When I stood in court and explained to them what I was doing, the Judge had to explain to Jury the balance of justice, as most people don't know about it. He said that you are allowed to break the law in a lesser way to counteract others breaking the law against you.
If you are doing a protest like this, the magnitude of your protest will depend on what extent people are breaking the law against you. For example I was breaking a restraining order that was put around my university, and breaking university Guidlines by sticking up posters. Your case might be different.
The decision of a protest can be made by you, you don't need to go to anyone. I would encourage you to protects against injustice, as this is righteous but at the same time tell you to refrain from rebellion.
Allah commands justice, the doing of good, and liberality to kith and kin, and He forbids all shameful deeds, and injustice and rebellion: He instructs you, that ye may receive admonition.(16:90)
