Is a municipality liable for a fallen tree?

In principle yes, as the structure owner under Art. 58 OR or via Art. 41 OR/Art. 679 ZGB — provided there is a breach of the duty of care (e.g. failure to remedy a recognisable defect) that is attributable to the owner.

Does the burden of proof automatically reverse in tree-damage cases in Switzerland?

No. This is a common misconception carried over from German law. Swiss law has no equivalent statutory reversal of the burden of proof; what matters is the free assessment of evidence under Art. 157 ZPO.

Tree Owner Liability in Switzerland: Art. 58 OR Explained

Anyone who owns a tree in Switzerland is liable for damage arising from its defective condition under Art. 58 OR (structure-owner liability) as well as Art. 41 OR and Art. 679/684 ZGB. In 4A_114/2014, the Federal Supreme Court recognised a documented inspection routine with a frequency of 1–3 hours during snow and ice conditions as an acceptable means of proving that due care was taken. Contrary to a common assumption, Swiss law does not have a statutory reversal of the burden of proof equivalent to the German § 823 BGB.

Central liability provision: Art. 58 OR
Supplementary provisions: Art. 41 OR, Art. 679/684 ZGB
Leading case on inspection frequency: BGer 4A_114/2014
Recognised inspection frequency (winter service): 1–3 hours during snow/ice
Statutory reversal of the burden of proof in Swiss law: does not exist

The central provision: Art. 58 OR

Art. 58 OR establishes strict liability for the owner of a structure for damage resulting from a defective installation or inadequate maintenance of that structure. Whether a tree qualifies as a "structure" within the meaning of this provision is not entirely settled in legal doctrine — in practice, liability is regularly also based additionally on the general duty of care under Art. 41 OR as well as on the neighbour-law provisions of Art. 679 and Art. 684 ZGB.

What BGer 4A_114/2014 actually says

The decision concerned a winter-service matter (a building-caretaker context), not a tree-inspection matter directly. It is nonetheless central to proof-of-care logic because it shows which inspection interval a court has recognised as reasonable: a documented routine with a frequency of 1 to 3 hours under winter conditions. Other relevant winter-service decisions are BGE 118 II 36 as well as BGer 4C.150/2003 and 4A_20/2009.

The common misconception: "reversal of the burden of proof as in German law"

German law's § 823 BGB provides, in certain constellations, for a reversal of the burden of proof to the detriment of the party responsible for traffic safety. An exactly equivalent statutory reversal of the burden of proof does not exist in Swiss law. Instead: a party invoking due care can substantiate it through a documented, adequate inspection routine — this is a means of proof within the free assessment of evidence (Art. 157 ZPO), not an automatic statutory reversal of the burden of proof.

For your business

The practical core for businesses: a complete, timestamped inspection history is the evidence that counts in a dispute — not the mere assertion that work was carried out with due care.

For the commissioning authority

A municipality, as a structure owner, bears the same liability under Art. 58 OR — a documented inspection routine by the commissioned business also indirectly benefits the commissioning authority.

What this does not mean

The term "court-proof" is not a sustainable marketing claim (Art. 13a UWG) — a court freely assesses evidence (Art. 157 ZPO); documentation can support that assessment but cannot pre-empt it.
Whether a tree qualifies as a "structure" within the meaning of Art. 58 OR is not answered uniformly in legal doctrine — in practice, the legal position relies on several provisions simultaneously.
BGer 4A_114/2014 concerned a winter-service matter, not a tree-inspection matter directly — applying its inspection-frequency logic to trees is a professional analogy, not a direct precedent.
