You can’t call that fly tipping , it’s a wee bit different to fridges and stained mattresses
Lots of clipes on here, another good Scottish word
Perhaps I misused the term flytipping, more of a colloquial rather than legal term anyway. I think this is the relevant legislation for matter left on Highway
https://www.legislation.gov.uk/ukpga/Will4/5-6/50/section/LXXIII/enacted
LXXIIIMatters laid on or near Highway, so as to be a Nuisance, to be removed on Notice; or on Failure, Surveyor to dispose of the same by Order of a Justice.
And be it further enacted, That if any Timber, Stone, Hay, Straw, Dung, Manure, Lime, Soil, Ashes, Rubbish, or other Matter or Thing whatsoever shall be laid upon any Highway so as to be a Nuisance, and shall not, after Notice given by the Surveyor, Assistant Surveyor, or District Surveyor, be forthwith removed, it shall and may be lawful for the Surveyor, Assistant Surveyor, or District Surveyor, by Order in Writing from any One Justice, to clear the said Highway by removing the said Stone, Hay, Straw, Dung, Manure, Soil, Ashes, Rubbish, or other Matter or Thing as aforesaid, and to dispose of the same, and to apply the Proceeds arising therefrom towards the Repairs of the Highway within the Parish in which such Highway may be situate: Provided nevertheless, that if any Soil, Ashes, or Rubbish shall be laid on any Highway, and such Soil, Ashes, or Rubbish shall not be of sufficient Value to defray the Expence of removing them, the Person who laid or deposited such Soil, Ashes, or Rubbish shall repay to the said Surveyor, Assistant Surveyor, or District Surveyor the Money which he shall have necessarily expended for the Removal thereof, which Money, in case the same shall not be forthwith repaid, shall be levied as Forfeitures are herein directed to be levied.
Written in a time where the value of something like Dung may have exceeded the cost of removing it.
