What a great idea for a challenge!
I decided to play a game of spell roulette. I ended up with a justice spell jar. Here’s a quick run-down.
Items Needed:
-written intention/sigil in orange ink/pencil, etc
-red jasper for fairness, promotes justice
-garnet and hematite both ensure justice is served, helps you to not lose your power and helps you feel confident and strong.
-rose quartz aids reconciliation, empathy and the forgiveness of others.
-marigold/calendula bring justice
-chammomile brings justice
-jasmine for love and peace
-feather as an offering to goddess Maat.
Add ingredients besides the feather. Light the orange candle to ensure feather stays on top of jar lid. Then place the candle above the feather to burn. Light it for 7 days or until it burns completely.
As the candle burns say aloud or to yourself:
Goddess Maat,
Cast your eye upon the world and bring order to this chaos. Weigh our hearts andpass judgement upon those who do evil. Reveal the truth and bring justice. May it be. 
You may meditate upon the flame of the candle and acknowledge all of the pain and fear that you feel and release it into the universe.
Heres my end result
