The Supreme Court actually rejected the challenge to Sheppard-Towner in Commonwealth of Massachusetts v. Mellon, 262 U.S. 447 (1923).
I am a little confused here everything I find states it was ruled Unconstitutional. help me to see what you are seeing. I do not want to steer anyone in the wrong direction. I am a person whom deals with facts and if you see someting that I write is wrong I want to be corrected immediately. thanks, just trying to read what you write too. I am not a person to take offense, just everything i am finding states it was ruled unconstitutional and took until 1929 to defund it in its entirety, 1927 the funding was extended for 2 years for 15 of the states. (If there a problems with grammar, punctauation at times - voice activated software is not the greatest, and sometimes when I double check errors are not evident right away).
