ProPublica is not a reliable source, and this is yet another example. They write these misleading pieces lacking in context to pull clicks and push their agendas.
In proper context, "secretive votes with little justification" don't carry much weight as rulings, if we even want to call them that. It's the public and written justification that shapes law in the US system.
These are administrative tweaks, footnotes. But that doesn't make as compelling of a story for ProPublica.
