Section 1. Be it enacted, &c., That whenever any borough or township of the first class has heretofore filed in the office of the prothonotary of the proper county any tax lien or tax liens, and the borough or township of the first class has not, within the period of five years after the date on which any such tax lien was filed, sued out a writ of scire facias to reduce the same to judgment, then, in any such case, any such borough or township of the first class may, within six months after the passage and approval of this act, issue its praecipe for a writ of scire facias on any such tax lien and proceed to judgment in the manner provided by law to obtain judgments upon tax liens; and such judgment shall be a valid judgment and be a lien upon the real estate upon which it was a lien at the time it was filed, and said judgment may be revived and collected as other judgments upon tax liens are revived and collected: Provided, however, That the lien of any such judgment shall not reattach against any real estate transferred to any purchaser during the time when the lien of any such tax lien was lost, nor shall the lien of any such judgment impair or affect the priority of the lien of any mortgage or other lien which gained priority because of the failure of the borough or township of the first class to sue out the writ of scire facias within the five-year period or was entered of record during the time the lien of such tax lien was lost.
This act shall be in effect immediately upon its passage, and approval by the Governor.
