The No-Injunction Rule re: Peaceful Picketing

The general rule is that no writ of injunction can issued against the holding of picketing by workers. Under Philippine constitutional law, picketing is considered part of freedom of speech. (G.R. No. 159460)

The following are exceptions to the general rule explained above. Under the situations below, picketing may be enjoined by the NLRC:

[1] Where picketing is carried out through the use of illegal means;
[2] Where picketing involves the use of violence and other illegal acts;
[3] Where picketing affects the rights of third parties and injunction becomes necessary to protect such rights.
