Where a city had power to build water- works, the fact that by so doing it would violate contract rights of an existing water company does not give an individual prop- erty owner the right to enjoin the city on the ground that his taxes would be in- creased thereby; 60 Fed. Rep. 961. Equity will not enjoin a municipal cor- poration in the exercise of its lawful pow- ers, unless the proposed act is ultra vires and would work irreparable injury: 48 Fed. Rep. 308; but a resident taxpayer and real estate owner is entitled to bring a suit to enjoin the execution of a municipal contract illegally awarded, whatever may be alleged to be his ulterior purpose; 8 D. R. Pa. 266; 137 Pa. 561. Where a statute creates a new offence and neglects the penalty, the ancillary remedy of injunction may be claimed as well as the penalty; Brett, L. C. Mod. Eq. 327. An injunction against a newspaper to re- strain it from copying literary matter from another newspaper will not be refused be- cause such is the practice of newspapers ; [1892] 3 Ch. 489, where the cases are col- lected. An injunction will not lie to re- strain the publication of an encyclopedia of the same name as complainant's, except as to copyright articles, where defendant has used no means to lead the public to be- lieve that its publication is that of com- plainant; 44 Fed. Rep. 793. In England, equity, in special cases of contracts for personal services, will restrain the violation of the contract, whenever the legal remedy of damages would be inade- quate and the contract is of such a kind that its negative specific enforcement is possible. This rule was at first applied to contracts which were in form expressly neg- ative, but has since been extended to affirm- ative contracts which imply negative stipu- lations; Pom. Eq. Jur. § 1343; 1 De G., M. & G. 604; L. R. 16 Eq. 149; 1 McCra. 558, 565; 1 Holmes 253. But where there was a contract for personal service containing a stipulation by the employed that he will "act exclusively for" his employer, the employed will not be restrained by injunc- tion from entering the employ of another person in the absence of a negative cove- nant in the contract, express or implied, which is clear and definite; 75 L. T. Rep. 526; 47 N. J. Eq. 270. The American cases are said to have us- ually either refused to follow the English decisions or have considerably modified them; see 53 Cal. 201; 8 Baxt. 54, 242; 42 Md. 460. Equity will restrain a breach of his contract by a baseball player who had contracted to play with the plaintiff; 8 С. C. R. 57; contra, 8 C. C. R. 337; see also 42 Fed. Rep. 198. An injunction will lie where the remedy at law, though there be one, is inadequate; thus: to protect an innocent purchaser of the stock and good-will of a business by enjoining the sale thereof by the sheriff, where the damages recoverable would be only for the value of the stock, without compensation for the loss of business; 138 U. S. 271; to prevent the illegal sale of a church-pew under an attachment, upon the ground that it would be an outrage to the owners' religious feelings; 27 Weekly Law Bull. (Ohio) 20; to prevent the illegal issue of corporate bonds; 118 Ind. 22; 5 Wall. 74; to prevent the destruction of ornamental trees on the plaintiff's grounds; 7 Md. 408; to restrain the cutting off of the supply of natural gas furnished under a contract; 50 N. W. Rep. (Ia.) 283; where the redress at law would be inadequate by reason of the defendant's insolvency; 133 N. Y. 499. An injunction will lie to enjoin a public nui- sance if it be continuous and peculiarly in- jures the plaintiff or his property; 135 N. Y. 239. An injunction will not be granted on the application of a private person, to protect purely public rights; Beach, Inj. § 13; 139 III. 419; nor, except in a great emergency, to interfere with public im- provements; 40 N. J. Eq. 350; nor to re- strain the abuse of a public trust, unless the complainant can show some peculiar inter- est therein; 102 III. 379; nor to compel the lessees of an opera house to allow the plain- tiff to use the house under a contract there- for, where the effect would be to compel the lessee to break a contract with an inno- cent third party; 43 Fed. Rep. 831; nor to prevent the maintenance of a nuisance on a highway where it could be abated by in- dictment; 49 N. J. Eq. 11. Where a crim- inal prosecution is threatened under color of an invalid statute for the purpose of compelling the relinquishment of a proper- ty right, an injunction will lie; 80 Fed. Rep. 218. Criminal acts may be restrained by injunc- tion if they are of such a nature as to con- stitute a public nuisance; 147 Mass. 550. This recent development of equity jurisdic- tion is well settled. Its efficiency has been in preventing the evils of strikes. See Judge Taft's Address, Report of Amer. Bar Asso., 1895, p. 265; 6 L. R. Eq. 551; 51 Fed. Rep. 260; 54 Fed. Rep. 730; 60 Fed.
