Analysis by the Legislative Reference Bureau
This bill changes the laws related to animals that are taken into custody on
behalf of a city, village, town, or county (political subdivision).
Seizure and withholding of animals
Current law authorizes a humane officer or law enforcement officer to take
custody of an animal on behalf of a political subdivision for a number of reasons,

including that the animal is a stray or that the humane officer or law enforcement
officer has reasonable grounds to believe that the animal has been involved in animal
fighting or has been mistreated in violation of state law. Under current law, a
political subdivision may contract with another person (contractor), such as a
humane society, to provide custody and care of animals taken into custody on behalf
of the political subdivision.
Under current law, an animal taken into custody must generally be returned
to its owner if the owner provides reasonable evidence of ownership, provides for any
required licensure and vaccination of the animal, and pays the costs of custody and
care of the animal. Under this bill, an owner who wishes to obtain the return of an
animal in custody must also arrange to have a microchip implanted in the animal for
identification.
Current law authorizes a political subdivision to withhold an animal from its
owner if there are reasonable grounds to believe that the owner has mistreated the
animal in violation of state law; there are reasonable grounds to believe that the
animal poses a significant threat to public health, safety or welfare; the animal may
be used as evidence in a pending prosecution; or a court has ordered the animal
withheld for any reason.
If an animal is taken into custody because the animal is alleged to have been
involved in fighting, current law requires the animal to be kept in custody pending
the resolution of criminal charges relating to the alleged animal fighting. This bill
eliminates the provision requiring an animal alleged to have been involved in
fighting to be maintained in custody pending the outcome of the charges. Under this
bill, the provisions relating to an animal in custody that is believed to have been
involved in animal fighting are the same as those relating to an animal believed to
have been mistreated in violation of state law.
Petitions seeking return of animals in custody
Under current law, a person claiming that an animal that he or she owns was
improperly taken into custody or withheld by or on behalf of a political subdivision
may petition a court to order the return of the animal. The court must order the
animal returned to the owner unless the court makes one of several specified
determinations. One basis for denying a petition is that there are reasonable
grounds to believe that the owner has mistreated the animal in violation of state law.
Under this bill, the owner of an animal must file a petition for return of the
animal no later than the seventh day after the day on which the animal was taken
into custody. The bill requires the owner to serve a copy of the petition on the
contractor with custody of the animal as well as on the political subdivision. This bill
generally requires the court to hold a hearing on the issue of whether the animal was
improperly taken into custody or withheld within 10 days of the filing of the petition.
Other petitions concerning animals in custody
Under current law, a political subdivision may petition a court for an order with
respect to an animal taken into custody or withheld from the owner. The political
subdivision must notify the owner of the animal when it files a petition. In a petition,
a political subdivision may ask the court to provide for payment for the custody and
care for the animal, to require the owner to post bond for the costs of custody and care

for the animal pending the outcome of another court proceeding (such as a criminal
case related to the animal), or to authorize the sale, destruction, or other disposal of
the animal. The court may grant, modify, or deny petitioned-for relief, after
considering the interests of the animal, the owner of the animal, the political
subdivision, and the public. If an owner does not comply with an order directed to
the owner, the animal is treated as an unclaimed animal, which means that the
entity with custody of the animal may dispose of the animal by, for example, releasing
it to another person.
This bill allows a contractor with custody of an animal, in addition to a political
subdivision, to petition a court for an order with respect to the animal. The bill
requires the contractor to notify the owner and the political subdivision when it
petitions the court for an order with respect to the animal and to notify the district
attorney if it is alleged that the animal was mistreated in violation of state law or was
involved in animal fighting. The bill requires a political subdivision to notify a
contractor with custody of an animal, in addition to the owner, when it petitions a
court for an order with respect to the animal and to notify the district attorney if it
is alleged that the animal was mistreated in violation of state law or was involved
in animal fighting.
The bill authorizes a political subdivision or contractor that petitions the court
for an order with respect to an animal to ask the court to require the owner of the
animal to pay funds into the court for the costs of custody and care for the animal
pending the outcome of another court proceeding. If the court requires the owner of
the animal to pay funds into the court, funds must be periodically disbursed to the
person with custody to cover the person's reasonable costs. If the owner does not
comply with an order, the animal is treated as an unclaimed animal. The bill also
authorizes a political subdivision or contractor to petition a court to release an
animal to its owner pending the outcome of another court proceeding, but only if the
owner is not alleged to have mistreated the animal in violation of state law or to have
violated the law prohibiting animal fighting and only if other specified conditions are
satisfied.
The bill generally requires the court to hold a hearing on a petition filed by a
political subdivision or contractor within 10 days of the filing of the petition.
Order by criminal court
Under this bill, if there is a case charging mistreatment of an animal in
violation of state law or violation of the laws relating to animal fighting and an
animal allegedly involved in the violation is in custody under the civil laws described
above, the defendant or the district attorney may request the criminal court to order
that the animal be retained in custody for a period that is reasonable to allow the
collection of evidence relating to the animal. The bill requires the criminal court to
provide a copy of such an order to the person with custody of the animal and to any
court in which a case is pending under the civil laws described above.
The bill requires a person with custody of an animal and any court in which a
case is pending under the civil laws described above to ensure that the animal
remains in custody until the end of the period specified in the criminal court's order.

The ultimate disposition of the animal after the period specified in the order is
determined under the civil laws described above.
For further information see the local fiscal estimate, which will be printed as
an appendix to this bill.
