text: what was the major outcome, (result )of the plessy  v. ferguson trial?   this is when the supreme court ruled that "separate but equal" facilities were permissible under the constitution. the ruling held that segregation (for example, separate bathroom facilities etc. for "colored" and "white" people) was allowed in the us.  this was overruled about 60 years later, though, by the brown v. board of education decision. here, they ruled that segregation in america would not be tolerated. for specific case details, search the internet for "plessy v ferguson" or "brown v board of education."
