Between 2015 and 2018 , there were ongoing issues with eruv markings extended on utility poles in a section of New Jersey . The adjoining municipalities of Mahwah , Upper Saddle River and Montvale , all border the state line on the other side of which is Rockland County , New York , where there are large communities of Orthodox Jews . After some eruvin were extended into Bergen County , allowing travel in the area , the municipalities took action in 2017 to dismantle the lechi markings . The matter was taken to court , and in January 2018 the presiding judge in the lawsuits made it clear he felt the municipalities did not have a strong case , and urged them to settle . The three municipalities have settled with the eruv association , allowing the eruv borders to remain in New Jersey , reimbursed the association 's legal fees , received agreement from the association to adjust the color of the lechi mounted on local utility poles , and agreed to work through a few remaining route details . In general , state law has dealt with whether and to what extent government can permit or assist the erection and maintenance of boundary demarcations on public property . It has not dealt with the nature of the aggregation agreement or recognized an eruv as having legal effect or as implementing a meaningful change in real property ownership or tenancy . For purposes of accident liability , trespass , insurance , and other secular matters occurring on Shabbat , state law treats the properties within an eruv as continuing to be separate parcels
