Pennsylvania Statutes Title 53 P.S. Municipal and Quasi-Municipal Corporations § 1203. Bond;  when security may be required

In all cases where the several cities of this commonwealth are or shall be required by law to give or tender security in the taking, appropriation, or injury of lands and property, where the same is being acquired for any authorized public use or purpose, the said security may be the bond of the proper city, and be given and tendered without surety or sureties:  Provided, however, That if it shall appear to the proper court or a law judge thereof, when the said bond is presented for approval, that the power of taxation in the respective city is not sufficient security, the said court or law judge may require the said city to give or tender bond with surety or sureties.
