AFAIK, the legislature never passed a law to allow mail in votes. If someone finds anything to qualify PA mail in votes (ie a law passed by the legislature) please cite it, otherwise the rule of law has once again been flushed! § 14. Absentee voting. (a) The Legislature shall, by general law, provide a manner in which, and the time and place at which, qualified electors who may, on the occurrence of any election, be absent from the municipality of their residence, because their duties, occupation or business require them to be elsewhere or who, on the occurrence of any election, are unable to attend at their proper polling places because of illness or physical disability or who will not attend a polling place because of the observance of a religious holiday or who cannot vote because of election day duties, in the case of a county employee, may vote, and for the return and canvass of their votes in the election district in which they respectively reside. (b) For purposes of this section, "municipality" means a city, borough, incorporated town, township or any similar general purpose unit of government which may be created by the General Assembly. (Nov. 5, 1957, P.L.1019, J.R.1; May 16, 1967, P.L.1048, J.R.5; Nov. 5, 1985, P.L.555, J.R.1; Nov. 4, 1997, P.L.636, J.R.3)
The power to decide what is "legal" with voting, ultimately goes to those officials whom the legislature has given the power to certify the vote. Unless the legislature decides to subsequently act with force of law, which is unlikely and can be difficult. If the legislature isn't going to (or able) enforce its own laws, then those laws can be as good as irrelevant. What people need to realize is that laws don't enforce themselves. There's a system and process in place, and a more complex interaction between laws, the system, and individual officials.
What are you doing? You start a thread complaining about mail in voting and then quote a law that pertains to 'absentee' voting. Are you trying to compare apples to oranges?

There have been a few, well-publicised cases, such as in the 2018 North Carolina primary, which was re-run after a consultant for the Republican candidate tampered with voting papers. New York, nearly 100,000 ballots were resent to voters after some names and addresses were printed incorrectly. Wisconsin, mail that included some absentee ballots was found in a ditch near the town of Greenville. How this happened remains unclear, despite investigation. The White House alleged fraud. Pennsylvania, nine discarded military ballots were discovered. Seven of them, according to the US Department for Justice, "were cast for presidential candidate Donald Trump". New Jersey, a mail carrier was charged after dumping hundreds of items of post in a dumpster, including almost 100 election ballots. Once found, the mail was sent on to its intended recipients. About 50,000 voters did receive the wrong ballot in the post, in Franklin County, Ohio, in early October. And the local elections board said everyone affected was sent the correct voter slip, with safeguards in place to ensure no-one voted twice. But there is no evidence this was done fraudulently. The board said the ballot error had been a "serious mistake". https://www.heritage.org/voterfraud A Sampling of Recent Election Fraud Cases from Across the United States The Heritage Foundation’s Election Fraud Database presents a sampling of recent proven instances of election fraud from across the country. Each and every one of the cases in this database represents an instance in which a public official, usually a prosecutor, thought it serious enough to act upon it. And each and every one ended in a finding that the individual had engaged in wrongdoing in connection with an election hoping to affect its outcome — or that the results of an election were sufficiently in question and had to be overturned. This database is not an exhaustive or comprehensive list. This database is intended to demonstrate the vulnerabilities in the election system and the many ways in which fraud is committed. 1,308 Proven instances of voter fraud The process is insecure, and we know for a fact vote fraud take place all the time, just because it couldnt be proven it does not mean it did not happen. Even murders go unresolved, the person is still dead despite the inability to catch the perp and prove it in court. We need a unified secure process for our voting system, its easy to devise a fool proof voting system, we do not have anything remotely close to that now and will never get it, especially when people are more concerned with which candidate got in than the process itself, it will forever be brushed under the table as merely sour grapes by the loser. Next time the person you hate will get in! garbage in garbage out, you get what you pay for.
