It depicts a judge in a traditional wig and black robe hitting a protester lying on the ground, with the protester’s blood splattering onto a poster.

A very happy occasion! Thank you to The Lawyer - wonderful to read the citation is for "Displaying a clear commitment to environmental and climate work" & for "victories both within and outside her professional role."
