The unpaid seller's right of lien terminates:

Both circumstances are stated in section 49(1): delivery to a carrier or other bailee for transmission to the buyer without reserving disposal rights, and lawful possession by the buyer or his agent. Waiver is another statutory termination ground. Merely obtaining a decree for the price does not itself terminate the lien. Termination of lien must also be distinguished from any separate right of stoppage in transit.
