She would fight the TRO on grounds of 14th Amendment Equal Protection. Equal protection means that the rules and laws apply equally to everyone. Regarding cannabis, however, the rules are not applying equally to everyone.
For example, I represent 25-year-old Jonathan Wall, who’s currently in jail for growing and selling weed. There’s a multibillion-dollar industry in the United States, with many people and corporations growing and selling weed all over the country. It’s a violation of equal protection for one person to be able to do something in the United States while another person cannot.
It violates equal protection that Richardson could take one hit of pot and lose everything while other people in the country are making millions of dollars from growing, distributing, and selling it. Yet, while they get rich, she is deprived of everything she has earned.
Second ground would be the Fifth Amendment’s Taking Clause, which states: “Private property [shall not] be taken for public use, without just compensation.”
