Explain whether the supreme court, in finding such a fundamental right of privacy, acted properly in terms of the separation of powers established by our founders in the u. s. constitution. be sure to inform your response by applying a complete separation of powers analysis

Yes, i believe so.
It is important to know that there is nothing such a perfect legal system exist in this world. The separation of power in united states is created by founding fathers in order to prevent the government from turning into tyranny.
Even though this later on lead to a decrease in overall efficiency, i believe it still does its job in limiting Government's power

Independent executive agencies are more specialised.
