Which supreme court decision was rendered invalid by the landmark civil rights case brown versus board of education

The Supreme Court decision that was rendered invalid by Brown vs. the Board of Education was Plessy vs. Ferguson. In this case, the Supreme Court ruled that racial segregation of facilities was constitutional as long as the facilities were equal in quality.  However, this was rendered invalid by Brown vs. Board of Education in which racial segregation was ruled unconstitutional.

it is a part of john locke's natural rights popular during the age of enlightenment that people had inalienable rights to life, liberty and property. this was reflected by thomas jefferson in his declaration of independence as rights to life,liberty and the pursuit of happiness.

another line in the declaration of independence is that people have certain rights just because they are human. humans are capable of obeying the three natural rights john locke mentioned making them governable by these laws and therefore entitled to these rights as well.
