Agricultural Dispute Expert Witness

Agricultural disputes involving animals are among the most commercially significant matters we handle. A single contaminated feed delivery can kill a herd worth millions. A vendor selling cattle with undisclosed disease can destroy a buyer's breeding program. Straying stock causing a road accident can result in catastrophic injury claims. Each of these cases requires expert evidence from someone who understands both animal science and the practical realities of Australian farming.

Livestock Vendor Disputes

When livestock are sold with undisclosed health issues, the buyer may have claims under Australian Consumer Law, state sale-of-goods legislation, or common law. Our experts provide evidence on:

• Pre-existing conditions: Whether a disease or condition was present at the time of sale and should have been disclosed (Johne's disease, bovine viral diarrhoea, ovine Johne's, footrot)
• Fitness for purpose: Whether the animals were fit for the purpose for which they were sold (breeding stock that is infertile, dairy cows with chronic mastitis)
• Misrepresentation: Whether the vendor's description of age, breed, pregnancy status, or health was accurate
• Valuation: The value of the animals at sale versus their actual value given the undisclosed condition, plus consequential losses (infected herd, quarantine costs, lost breeding seasons)

Straying Stock and Road Accidents

Livestock on roads cause serious vehicle collisions, particularly at night in rural areas. The legal questions are:

• Was the fencing adequate to contain the stock? Our experts assess fencing condition against state standards and reasonable pastoral practice
• Were gates left open? Evidence of gate maintenance, signage, and stock management protocols
• Was the stock owner aware the animals had previously escaped? Prior escape history increases the duty of care
• Did the road authority contribute by failing to maintain cattle grids, signage, or stock-proof road shoulders?

Feed and Water Contamination

Contaminated stock feed can cause mass livestock deaths. Claims typically involve feed suppliers, transport companies, or neighbouring operations. Expert evidence addresses:

• Causation: Linking the contamination event to the livestock deaths through post-mortem findings, feed analysis, and toxicological testing
• Source identification: Tracing the contamination to a specific feed batch, water source, or chemical application
• Quantum: Valuing the dead and affected animals, replacement costs, lost production, and the cost of decontamination
• Standard of care: Whether the feed supplier's quality control, testing, and storage practices met industry standards

Agistment Disputes

Agistment — where one party grazes livestock on another's property for a fee — creates duty of care obligations on the agistor. Disputes commonly involve:

• Livestock that lose condition, are injured, or die while on agistment
• Failure to provide adequate fencing, water, pasture, or shade
• Mixing of stock leading to unplanned breeding, disease transmission, or injury
• Disputes over agistment fees when the owner fails to collect stock on time
• The agistor's lien — the right to retain stock until fees are paid

Crop Damage by Livestock

When neighbouring livestock break through fencing and damage crops, the claim involves establishing the extent of damage and the responsible party. Our experts provide evidence on the livestock's capacity to cause the alleged damage, the timeline of the incursion, and the adequacy of boundary fencing. We work with agronomists to connect animal evidence with crop loss valuations.
