The letter, from Bird manager Sayed Ahmed Alwadei, and seen by BBC Sport, refers to a caller regularisation added to the FIA's sporting codification this twelvemonth that forbids "the wide making and show of political, spiritual and idiosyncratic statements oregon comments notably successful usurpation of the wide rule of neutrality promoted by the FIA nether its statutes, unless antecedently approved successful penning by the FIA".
Alwadei says the determination "appears to beryllium a absorption to drivers, successful peculiar Lewis Hamilton, raising their concerns astir the locations chosen for F1 races, including the quality rights records of big countries, and making almighty interventions wherever your ain organisation has been silent".
The missive - addressed to FIA president Mohammed Ben Sulayem and copied to each the teams and Hamilton's representatives - contrasts the regularisation with past year's determination to cancel the declaration of the Russian Grand Prix.
And it underlines what it believes is simply a contradiction betwixt F1's attraction of Russia's warfare successful Ukraine and the engagement of Saudi Arabia, Bahrain and the United Arab Emirates, which each clasp grands prix, successful a warfare successful Yemen.
Alwadei says Hamilton has "used his level to explicit enactment for Black Lives Matter and quality rights successful countries with problematic quality rights records, including Bahrain and Saudi Arabia".
"Throughout his career, nary of the statements Hamilton has made tin beryllium considered immoderate much governmental than the determination by the FIA to retreat from racing successful Russia successful the past play owed to its penetration of Ukraine," added Alwadei.
"In your ain connection past year, you condemned the Russian penetration and expressed 'sadness and shock' for victims successful Ukraine. While I applaud this statement, it is intelligibly a governmental one."
In a connection issued to BBC Sport, Alwadei added: "When the FIA and F1 take to assistance races to immoderate of the world's astir repressive regimes, similar Bahrain and Saudi Arabia, they are facilitating sports-washing and allowing these dictatorships to launder their horrifying rights records.
"It is earnestly disturbing to spot the FIA present mimicking the tactics of its despotic concern partners by attempting to muzzle the voices of critics and advocates.
"Where the FIA and F1 failed, it was drivers similar Lewis Hamilton who stood up and called retired abuse, and his vocal enactment for governmental prisoners successful Bahrain shed airy connected appalling injustice.
"Now, the FIA wants to soundlessness him and others, and punish them if they situation to talk out. We are saying to Mohammed Ben Sulayem that this argumentation is incorrect and it indispensable beryllium reversed immediately."
Alawadei refers to a gathering with the FIA connected 19 March 2021, erstwhile Frenchman Jean Todt was president, astatine which helium was "given the encouraging assurance that your predecessor was keen for the FIA to follow a quality rights policy".
He adds that the gathering was Bird's "last meaningful engagement with the FIA" and that "unfortunately, Jean Todt's presidency ended without a quality rights argumentation successful spot and it is not wide whether this is inactive thing the FIA is moving towards nether your enactment oregon not".
The FIA has been contacted for comment. A spokesperson has antecedently said the caller regularisation is meant to codify an existing arrangement.
It is said to beryllium directed astatine the wearing of covering bearing campaigning statements connected the podium oregon earlier the contention - specified arsenic those Hamilton wore during the tallness of the Black Lives Matter question pursuing the execution of George Floyd by US constabulary successful 2020 - alternatively than wide comments successful enactment of advancement connected quality rights.
Controversy implicit F1 valuation remarks
In a abstracted development, Ben Sulayem has caused interest wrong F1 with a bid of tweets saying the athletics is not worthy $20bn (£16.2bn).
Ben Sulayem's remarks travel successful the aftermath of a study by Bloomberg that Saudi Arabia's Public Investment Fund (PIF) had tried and failed to bargain F1 for that figure.

He added: "It is our work to see what the aboriginal interaction volition beryllium for promoters successful presumption of accrued hosting fees and different commercialized costs (in the lawsuit of immoderate specified sale)."
Saudi Arabia is progressive successful F1 - its nationalist substance institution Aramco is simply a firm sponsor, and the state hosts a contention that has 1 of the largest hosting fees - but BBC Sport has been told its PIF has not astatine this signifier tried to bargain the sport.
But Ben Sulayem's involution raises a bid of questions arsenic to wherefore helium has felt the request to get progressive connected a commercialized substance that technically is not wrong his remit.
The FIA is required to enactment distant from commercialized matters wrong F1 by an statement struck with the European Commission much than 20 years ago.
Ben Sulaymen's connection comes against the backdrop of continuing hostility betwixt the FIA connected the 1 broadside and F1 and the teams connected the different astir the mode the athletics is being run.
