1. Mediator's case: The initiator Anna is the owner of a wall standing on her land. The co-participant Mark painted this wall white without her consent and damaged it in certain places while building his own wall.
2. Assessment: Regardless of the fact that the co-participant Mark acted with the desire to improve the appearance of his yard and bore the costs himself, this does not justify interference with another's property. The initiator Anna has the right to decide on the appearance and condition of her wall, even if she does not see it. The damage, even if minimal, is an additional violation.
3. Mediation opinion: The mediator recommends that the co-participant Mark restore the wall to its original condition at his own expense – this includes repairing the damage and repainting it back to the original gray color or the color chosen by the initiator Anna. The mediator also advises a written apology to the neighbor. Since the initiator Anna did not demand monetary compensation and since this is an interference that can be remedied, the mediator does not propose a financial amount. It would be sensible for the co-participant Mark to agree in advance on any future interference on the common boundary.
4. Closing remark: Mark, your intention was noble as white paint – but unfortunately the wall, like the house rules, is a matter for both, not just the one with the brush in hand. Next time, rather invite your neighbor Anna for a coffee and color samples – cheaper and without notes in the mediation record.
