Mechanics and materialmen
Construction workers and deliverymen serving notices of intent to lien and seizing or foreclosing real property in court
There appear to be various statutes in different states allowing construction workers and deliverymen to seize ownership of any real property they work on or deliver supplies to for any claims of debt for work performed or materials delivered.
OR Legislature
If builders or property owners are bankrupt or unable to pay for improvements to their real property, which they have contacted or agreed to, potentially they stand to lose their property anyway in a bankruptcy judgment under uniform laws throughout the United States.
The state and local level pre-emption of uniform national bankruptcy laws, for construction workers and deliverymen to lay a prior claim of debt for work allegedly performed or supplies allegedly delivered on credit, however, is totally unconstitutional.
Not to mention, it is rude and unbusinesslike for subcontractors and suppliers to serve hostile, obnoxious, or simulated legal process on builders or property owners as part of any normal course of doing business.
The communist party "workers' takeover" system of outsourcing labor to construction workers and deliverymen who file mechanics' and materialmen's liens in court is not conducive to a capitalist way of doing business with respect to ownership of real property.
