NOTE: I am not a Lawyer, so this is not legal advice...
An EEOC "Right To Sue" letter is only a notice to the complainant that the EEOC has decided that they will not pursue a suit ( by the EEOC legal team ) of the party that the complainant has filed against. The "Right To Sue" letter tells the complainant that they can go ahead and pursue civil actions if they choose to.
Right To Sue" letters are not necessary incriminating of and of their own right. A number of courts, including Circuit courts do not allow the letters to be automatically admitted as evidence. As per president listed below.
"The “automatic” admission into evidence of EEOC letters of discrimination has always been a bone of contention in employment discrimination lawsuits. Being able to tell a jury that the US Equal Employment Opportunity Commission investigated and found reasonable cause to believe that discrimination occurred can be a critical component of any plaintiff’s case. Recently, the Court of Appeals for the Third Circuit joined the majority of Circuits in holding that the EEOC letters of discrimination are not automatically admissible. At present, only the Fifth and Ninth Circuits have held that, absent proof of their unreliability (under F.R.C.P. 808), the EEOC letters are automatically admissible.
The Third Circuit addressed this issue in Coleman v. Home Depot, 306 F.2d 1333 (3rd Cir. 2002)"
My understanding is: EEOC "Right To Sue" letters is not an admission of grounds for a civil suit, but giving the complainant the choice to pursue on their own a civil suit without EEOC involvement.
Again I say... We should wait to see how this plays out in court.....
